— Robbie L

“Tim's patience and thoroughness with my wheelchair-bound husband over the last 8 months have been a significant help to continue Mihai's ability to still live at home. We are so grateful for the physical part and also for Tim's continued encouragement and joy while working new ways to make a difference in Mihai's life - in my life as well. Those who have NDIS for physio exercise ask Tim and his team to help you - they are truly dedicated great people!”

— M M C

“Tim has been a client of mine since 2015. It's been great watching him reconnect with a career in health after his years away from Physio. He's got a friendly, professional manner with his clients and has a knack of pushing people enough to get progress, but not so much that they pick up soreness or injury.

Personally, I have been a client of Tim's for running programming, he helped me to prepare well for the City to Surf.

I'd highly recommend Tim as a coach - particularly for older adults, runners and middle-aged guys looking to improve their body composition.

Tim has been a great addition to my gym (Raw Fit Co).

Thanks Timmy!”

— Anthony W

“I worked with Tim for 5 sessions to work on minimising my back pain. He was super helpful and gave me lots of exercises to make me feel better. He had lots of knowledge as to what was causing the pain and the best way to fix it, which I can now use moving forward. He’s a great guy to chat to and will definitely be coming back in the future.”

— Judd D

“I have just started running a program with Tim from Extension Fitness, and his knowledge about running is remarkable. He analysed my running pattern, posture, and correcting the techniques. I do strength training and follow the running program that Tim creates for me. I tried to follow what I can remember in a running event last week, and finally, I know what it means to be finished strong! I can finish the 12k from the beginning to the end with a relatively similar pace! I would recommend Tim to achieve your fitness goal!”

— Jo G

“Took my year 15 year old son to him for gym regime advice (running advice) following recovering from stress fractures to his back.

I was so impressed with Tim. Loved the fact he had taken the time to read all the MRI scans, had a clear treatment plan to assess movement that his back can function in without causing pain and gave him whole body functional strength gym exercises to work on. What 15 year old boy doesn't like going to the gym and improve on the sports he is playing..

Tim explained things very well, connected well with my son and gave us a clear treatment plan.

As a podiatrist I was very impressed and can see myself learning and referring patients to Tim.

Thanks so much Tim!”

— Brent R

“I was introduced to Tim at Extension Fitness through common associates and I’m very glad we met. I’m 55 and just getting back into a fitness regime after mostly cycling for the last 10 years. Tim spent time with me to assess and understand my current physical condition and goals before presenting and guiding me through a well thought out selection of specific exercises. His attention to detail, form, range of motion, and appropriate effort gives me a real sense of confidence I can progress injury-free.

I recommend Extension Fitness without reservation. Thanks Tim!”

— David N

“Extension Fitness did a great job assessing my son's running gait and providing tips, running drills and a strength and conditioning plan to improve his efficiency and reduce injury risk. Very competent and technical but also down to earth. Thanks Tim!”

— John R

“I have loved doing PT with Tim. He has excellent knowledge about injury recovery and how to adapt exercises according to your needs and ability. Tim helped me to increase my leg strength to overcome niggling hip/pelvis pain. Also, he’s great company. Highly recommend”

— Amanda J

“I needed some external motivation to get back into physical exercise. Met Tim by chance when he was setting up in the nearby park for another client. With his help and guidance I'm back on track and attending his regular bootcamp sessions. No hesitation to recommend his services.”

— M Wandy

“I'm in my mid 60s and wanted to do strength and resistance training appropriate to my age for general health and fitness. I have been training with Tim for 3 months now and have noticed improvements. Not such an effort to get off the floor for one! I've been doing 2 sessions a week, with a view to eventually doing the program on my own, with ongoing support from Tim. He is very knowledgeable when it comes to how the body works, not doubt due to his physiotherapy background. He tailors exercises to suit, taking into account any physical issues such as my osteoarthritic knees. I am lifting weights I never thought I could do though sometimes he does sneak in heavier ones! He is very encouraging, not only with the exercises but with my weight loss regime. Never thought I would actually enExtension Fitness did a great job assessing my son's running gait and providing tips, running drills and a strength and conditioning plan to improve his efficiency and reduce injury risk. Very competent and technical but also down to earth. Thanks Tim!”

— Anne S

“Cannot rave about Tim enough, he is very knowledgeable, and I feel very secure, having him guide me with my workout sessions. 😊

I looked around before deciding on Tim, and he made me feel very comfortable, and an added bonus, he used to be a physiotherapist which meant he knew the human body well.

My core focus of going to Tim was to prevent further injuries, and I need it to ensure my form and technique was correct. He understood my scope and designed a workout for me, which I could do on my own, and also have top up sessions with him too.
I would not hesitate to recommend him to anyone. He’s professional, and very warm and friendly. Thanks Tim! 😊 💪🏻 🏋🏻‍♂️”

— Michelle L

“Tim has been my husband's personal trainer at his gym for several months now, and the progress has been remarkable. Tim's approach is smart, authentic, and full of energy. He took the time to understand my husband's needs, motivations, and challenges, and tailored a fitness plan that works.
The results speak for themselves - increased strength, decreased weight, an increased and healthy focus on food, and a marked decrease in snoring (yes!).
Tim's genuine ambition to help his clients reach their health goals is evident in the positive changes we've seen.
We're grateful for Tim's dedication and the supportive environment he's created at the gym.”

— Tanya S

“Tim offers a wide variety of exercises and training tips that have helped get me closer to my fitness goal! Tim is great and I can't recommend him enough.”

— Jamie B

— Nicole W

“Can’t recommend Tim and Extension Fitness enough!
Being a physio by training Tim really understands human movement and exercise physiology.
I wanted to learn hypertrophy and Tim helped me on that journey.”

— Nigel G

“Tim at Extension Fitness runs our hockey clubs preseason training sessions, his workouts look to replicate the intensity of a game, while still enabling people of various fitness levels to participate at the same time.”

— Neil H

“Nearing the end of my second year of pre season with Tim. I have greatly enjoyed working with and hearing feedback from Tim. he has organised great pre season sessions for our hockey club which is based in north Perth. Tim is a very nice guy and has made the whole atmosphere around pre season a very welcoming experience for everyone and encouraged everyone to get behind each other. He is very knowledgeable and has given me many great tips to improve both my short and long distance running times and capability. Overall would highly recommend Tim to anyone and would like to thank him for putting me on the right track to having a great season.”

— Cassia P

“This was one of the most self-empowering sessions I’ve ever participated in! I have had three hamstring strains in the last 9 months doing middle distance running, and Tim’s video review and technical analysis quickly highlighted my awareness to what in my running style could be causing this. Then came the running drills, where he gave me some easy to follow prompts regarding my hips, torso, head and arms which totally transformed the way i feel when i run! 5 days later and these prompts are still informing my awareness, not just when i do running training, but as I walk between classes (with much better posture and gait!), and play other sports. I wish i had of seen Tim 20 years ago (would have prevented a lot of soft tissue injuries!) and can’t recommend him highly enough!”

— Ben D

“Tim continues to run extremely relevant sessions allowing all participants to push themselves as far as they can whilst doing so at their own levels. He creates an environment filled with encouragement and enables everyone to have fun whilst they achieve!”

— Graham P

“I collaborated with Tim from Extension Fitness to provide a Beginners Running Course to my members (of Say Yes Fitness). He was welcoming and knowledgeable, approachable and adaptable. The sessions were well planned and well executed. Our community loved it and got a lot out of it! Highly recommend. Look forward to to collaborating again in the future."

— Renee C

“I am currently doing my second year of preseason training with Tim and it's excellent. Consistent and productive training allows for not only myself, but the team to work together and grow. From guiding us through a good warm up and stretch, to pushing us when running, it's excellent for individuals and as teams. The tiered exercises are the best, allowing everyone to work as hard but catered to different levels. Highly recommend.”

— Joshua N

“I'm making good progress with Tim at Extension Fitness in East Perth. The main agenda was general fitness and strength that will help me at golf and other activities. He's also been very helpful with gradual weight loss and I can already feel the benefits after only 4 weeks of the regime he designed for me. I'm looking forward to a fitter, healthier me in the coming months and of course lots of "birdies" on the golf course.”

— Adrian B

“I Love working with Tim, he runs great sessions for our Hockey club in North Perth. He is extremely approachable and easy to work with, giving great feedback to different techniques with short distance sprints but also long distance running also. He has helped me improve with my running and getting better at the things I need to work on and I love how easy it is to talk to him about the things I need to improve on to help out my running. Highly recommend”

— Luke N

stressed!”

— Jonathan P

“Highly recommend. Tim provided in depth and targeted feedback in an easily understandable way. He was easy to communicate with and provided great value for time”

— David L

“Really enjoyed my running assessment with Tim today. Looked at some video of my technique then analysed it and clearly communicated aspects I do well as well as areas of improvement. Tim took time to explain the reasoning behind each aspect of technique and provided me with simple exercises I can do to improve.
Great set up and a wonderful teacher.
Great experience all round, highly recommend!”

— Mikala B

— James P

“Tim at Extension Fitness ran Mods Hockey Club pre-season sessions in 2023.

Tim provided sessions for both our Mens and Womens teams catering to a wide range of fitness levels. He managed to engage all the participants with challenging but fun sessions which catered for the various fitness levels of the individuals.

As a club we saw higher than usual attendance, increase fitness levels and a positive attitude from our players about the program.

We are excited to engage Tim again in 2024.”

— Mods Hockey Email

“Tim has been an amazing help for my partner and I to train for a big hike. I really appreciate Tim’s approach to training average athletes rather than a perfect body. I am feeling strong and looking forward to continue my training goals!”

— Niamh N

“I cannot recommend Tim at Extension Fitness enough.
I was nervous before my first session as having MS and foot drop I wasn’t sure what to expect or if anything could be done to help my running. Tim made me feel welcome from the start, helped me with my running technique and gave me a plan with particular exercises to improve my form.
It has only been around 8 weeks but I can already feel the difference in my running form and efficiency. Thank you Tim!!”

— Rebecca C

“For the last year, I’ve been doing either personal training or customised exercise programs with Tim at Extension Fitness. The training has really helped me to develop strength and fitness. Tim provides good explanations of how to do all the exercises and why. He creates the workouts to suit my goals and personality. Tim is very responsive with any questions and generous with his time, skills & experience. I have felt challenged but not pushed excessively hard by the sessions. One of the things I really appreciate about Tim’s training style is that everyone is accepted where they are at without comparison to anyone else. I am definitely not a sporty type person, but I have always been made to feel that there is a place for me (& everyone) in the gym regardless of your age/gender/sportiness/strength/goals. Tim is a positive, encouraging coach that I would recommend to anyone. Give it a go!”

— Amy and Duncan C

“Firstly I do not like gyms- so if you can relate to that, then - I recommend Tim at Extension Fitness.

As someone who has physical restrictions / disability, after having a stroke. I have struggled with gym environments, finding most of them somewhat intimidating and uncomfortable. Having to maintain muscle and strength to keep my independence, fitness has never really been optional for me. It’s necessary.

Tim creates a safe and supportive environment where you never feel out of place or insecure. This includes the gym where Tim is based, you are among, like minded, kind people.

Tim’s background in physiotherapy, adds another layer of knowledge, that enhances the PT programs Tim provides.

It’s been an amazing journey. I have a personalized training program, adjusted to accommodate my physical restrictions. A program that is sustainable and realistic. A program, where I’m actually seeing results.

With Additional bonuses like humour, patience and the ability to work with NDIS participants. It’s a level of service that’s hard to beat.

I can not fault my experience with Extension Fitness.

Thanks Tim!”

— Rae G

“I cannot rate or recommend Tim from Extension Fitness highly enough to anyone who is wanting to undertake the journey of exercise. Tim, by nature, is understanding and compassionate. He will meet you where you are on your fitness journey. I was struggling with motivation and other personal issues; the sessions are supportive, filled with encouragement whilst gently helping to push past my own personal barriers. Tim is filled with exceptional knowledge surrounding the human physiology and exercise movements, and will support your personal fitness goals.

I love our sessions! The sessions have aided in reframing the need to lose weight or to look a specific way, instead focusing on the overall improvement of my strength and wellbeing, both physically and mentally.

Each session is crafted to the individual. As an example, we have a weighted session that includes various super-sets, then we move onto boxing.

Tim is incredibly patient with his teaching style; I will often need the instructions repeated to grasp the concept of the boxing techniques, which Tim is more than happy to do so.

I’ve thoroughly enjoyed getting stronger and hitting new personal bests, while learning a new skill (boxing)! Thanks Tim!”

— Arlene P

“Tim from Extension Fitness is excellent at what he does! I have been putting off exercising for ages because it all felt insurmountable to me but Tim has really helped me to not feel daunted, and quite the opposite- I look forward to my workouts! I would add also that Tims background as a physiotherapist really shines through with his extensive knowledge of the body, how it works, and how to hit the weights without injuring yourself.”

— Andrew D

“After finding Tim online we caught up for a coffee and chat about my goals starting out on my fitness journey. He was very helpful in providing advice going forward with the custom program I requested. We settled on 2 initial PT sessions and the programs schedule.
Tim is very patient and attentive to my movements during PT sessions providing solid advice and techniques to move within my abilities. He made sure we covered off every movement in my custom program and that I was comfortable and had no pain or discomfort. He was quick to suggest other movements if I had trouble with anything and provided substitute exercises.
After a quick video/photo tour of my gym on-site Tim has been ale to make a custom program that accommodates limited equipment and higher work load whilst I am away at work, and being back in Perth with a larger range of equipment and the ability to push myself further.
After a recent injury, Tim had further modified my program to work in with my physio's recommendations. Now on the other the side of this injury we are rebuilding that lost strength.
I recommend Tim, highly approachable, genuinely friendly and understanding. Not pushy in any way and really sets you up to be independent in your journey if that is what you want.”

— Timothy W

“Tim has been fantastic in helping me get my health and fitness back on track! He's personalised a program for that caters for the limitations of my worn-out body and continues to refine the plan based on our ongoing discussions and how my body has reacted. It's great being trained by someone with so much experience and a high level of intellectual and emotional intelligence. He makes our PT sessions both challenging and enjoyable. Thanks Tim - looking forward to the journey ahead!”

— James L

“I credit Tim with getting me back into routine training after a long break, and getting me started in strength training. I've appreciated his attentiveness when I've had difficulties and his down-to-earth explanations of why different sorts of exercises are useful. I would recommend him to anyone looking to get into (or back into!) physical training.”

— Sam R

“Tim at Extension Fitness was fantastic, he worked with us on tailoring a custom program for strength and fitness in preparation for our state hockey tournament. No denying it was tough, with hammies and quads burning, and also feeling like i was going to die at certain points, I feel he really enhanced our training program before the tournament.”

— Ben B

“Great workouts and really good fun. I found the workouts well planned, varied and very well suited to my fitness goals. Tim is super encouraging and supportive and communicates openly with you to gauge where you are at and how far you want to go with each workout. Highly recommend.”

— Ben M

“Hey Everyone, are you looking for a PT?
I highly recommend Tim from Extension Fitness as a personal trainer. I have been training with Tim for 6 challenging months and have seen amazing results. He is incredibly knowledgeable, motivating, and supportive throughout the entire fitness journey. Tim made me a custom workout program to suit my day to day routine and has helped me reach my goals and push beyond what I thought was possible. He has gone above and beyond by also providing valuable nutritional guidance to enhance overall fitness and well-being along with introducing me to apps that ensure accountability on my end (which was a game changer) so he could keep up to date with my fitness even while I was away working. The sessions are always challenging but enjoyable, and he makes sure to keep things fun and varied. If you're looking for a dedicated and professional personal trainer, Tim at extension fitness is the best choice!”

— Corey C

“I’m 74, enjoying good health and fairly active with things like walking, chopping wood and digging in the garden.
But at this age I thought it would be wise to be more deliberate about regular exercise to maintain and improve general strength and fitness.
I had come across some of Tim’s Blogs and was impressed by his thoughtfulness on fitness issues and his honesty about his own journey from physiotherapist to personal trainer.
During two sessions a week over the past two months Tim has taken me through a range of exercises, and he has now set me up with a program I can work with in my own time.
I have been surprised by the subtleties involved in proper exercise – stance, breathing, rhythm etc. I have also been impressed by Tim’s attention to these details and the gentle way he converts his observations into guidance for better technique. His background as a physiotherapist comes through in the way he explains the connection between the exercises and the muscles and joints.
I have found his explanations and guidance have always been aimed at providing me with the best fitness outcome, and understanding the program so I can handle it independently.”

— Dean P 

 “Tim recently completed a thorough and professional running assessment with me. He gave a comprehensive analysis of my running form and patiently talked me through key points for improvement. His understanding of fitness conditioning and injury prevention compliments what is already an excellent service!”

— Sturt

“From the first day i started training with Tim, i was met with a welcoming and inclusive environment within the class. Tim fosters a sense of community and camaraderie among the participants, making everyone feel valued and motivated to give their best. He is knowledgeable and cares about each person's progress and well-being.”

— Josephine M 

“Tim is an exceptional trainer, animated by an unwavering passion for wellness that extends beyond the predictable boundaries of fitness. He curates engaging group sessions that are not just fun but also radiate an inviting atmosphere. It doesn't matter if you're a novice or a veteran, I’ve found them to be impressively accommodating yet challenging for all fitness levels.”

— David B

“We have had a FANTASTIC experience with the team at Extension Fitness . So helpful , great communication and great training . Would highly recommend”

 — Janine A

“As a sixty-something looking to do strength training for health and mobility reasons, I was really happy with Extension Fitness. Tim helped me to build my strength in a safe and sensible way – with an emphasis on good technique. I noticed an increased ability in day-to-day tasks as a result of the exercises. I’d highly recommend Extension Fitness to older adults looking to build strength for health and mobility reasons.”

— Phyllis B

“Tim is exactly what you want in a trainer. A high degree of knowledge in fitness/exercise and as a former physiotherapist, the access to space and equipment for effective training and then of course - just being a great all round bloke!
Thoroughly recommend him for getting in shape, improving on your strength/power and for running training.”

—  Alex C

“Though I was an active 64 year old, I knew the importance of regular structured exercise. What I didn't know was how to do it effectively and efficiently or what was most suitable for my age and physical condition. Also, while I had used gym equipment at different times previously, I didn't really know how to use it properly. Tim was able to coach me through a three month program that introduced me to a wide range of exercises using many different types of equipment. He also provided me with a menu of groups of exercises that I was able to use to create my own activity sets that would include the necessary movement patterns for resistance training. Importantly, Tim and I spoke at length before and during the program so we both understood what I wanted to achieve. Tim also gave me plenty of support and information outside of the scheduled sessions. I thoroughly enjoyed working with Tim (except when I was pushing the sled) and would recommend him to anyone looking for a program that's meets their specific personal requirements. 

— Peter B

“Excellent trainer, no guilt or nonsense just great exercise sessions. Tim’s supportive and graded sessions have meant I’ve stuck at this exercise routine for longer than any previous attempts. Am seeing good results after 9 months of 1x week and now 3 months of 2-3x week.

Highly recommended”

— Ryan J

“My son did some personal training with Tim in the summer holidays. He loved Tim's way of explaining things and the variety of activities he did to improve his strength.”

— David H

“Tim's coaching is so very beneficial for my daughter. She was worried about the weightlifting sessions before she started but from the very first session has been always so happy to attend. She finds Tim's approach encouraging, fun, helpful, calm and friendly. I cannot be more positive about Tim's approach and the results being achieved these last 3 months or so.”

— David M

“Have been working with Tim for a few months now and it has been fantastic. Working towards running distance again and his knowledge and approach has been extremely useful. Knows the body’s mechanics extremely well and his workouts reflect that!”

— Jaxon T

“I cannot recommend Tim Karajas's Extension Fitness program enough! His motto is "Toughening them up and Straightening them out" which I just love.

Extension Fitness offers fitness instruction to home educated children at The Classical School.

As a parent, I am thrilled that my child has the opportunity to participate in this fantastic program, which offers age-appropriate fitness instruction for children from Pre-Primary to Year 10.

Tim's passion for fitness and health is evident in the quality of his instruction. He creates a safe and supportive environment for children to learn new skills, get active, and develop healthy habits. His programs are designed with each age group's unique needs in mind, ensuring that children are challenged while also having fun.

Tim is not only a great fitness instructor but also an excellent role model for children. He instills in them the importance of physical activity, and movement for life. I appreciate how he encourages children to enjoy the stretch, growth and development that comes with purposeful movement.

Overall, Extension Fitness at The Classical School is an exceptional program that benefits students in many ways. Tim's expertise, dedication, and passion make him a fantastic instructor, and I am grateful that my child has the opportunity to learn from him.”

— David E

“After a long, long break from any serious exercise, and as a fifty-something with plenty of wear-and-tear, I was looking for a trainer whose expertise I could unquestionably trust, and who made me feel supported and motivated.  Tim has fit that bill perfectly and I have thoroughly enjoyed his pragmatism, enthusiasm and kindness.   He knows what he is doing and takes the time to explain technique without being too rigid.  His workouts challenge me just enough – I’ve been pushed hard, but not so far that I’m broken the next day, or dread doing a session on my own.  I enjoy the structure and style of Tim’s approach and feel I am in excellent hands on my quest to” get strong again.

— Maree Q

“Thank you, Extension Fitness! I have been working with Tim for the last 6 months and I cannot recommend them enough. I thought I would need to give up sport due to knee and hip issues, Extension Fitness has tailored and modified a specific program to build my strength and fitness and now I am playing pain free again!!!
Tim is calm, professional, encouraging, knowledgeable and capable of pushing you to reach your goals.
Thank you” 

— Jessica E

“Highly recommended. Tim runs a very professional fitness program. He sets simple and realistic programs that accommodate a wide range of abilities and still gets excellent results. I found Tim to have a wide level of knowledge, a down to earth and caring personality, the patience to listen, and to provide authentic encouragement. I would like to use more of his services.” 

— Michael H

“Tim runs great sessions with a fantastic briars focus. From running to function movement they all have the ability to make you fitter and faster!”

—  Hamish W

“The pre season agility and running session you have set for the hockey club have been amazing. I feel like my fitness is improving but the workouts aren't too hard that I can't get out of bed the next day. Couldn't recommend your services more!”

— Andrew B

“Tim runs fantastic fitness sessions and has delivered a brilliant pre season program for our hockey club. Pushing without breaking is spot on as he carefully plans the activities to improve your fitness while making sure you don’t go too far. He is able to cater for large groups offering plenty of variety and his friendly nature makes it a welcoming environment. Whether working towards specific exercise goals or aiming to improve your running ability, extension fitness is an excellent place to enjoy your movement!”

— Ciaran S

“Tim is very knowledgeable and supportive of your personal fitness goals. His classes are well run, fun and encourage a team environment. Extension fitness makes the idea of exercise a joy!”

— Stacey-Ann D

“Extension fitness provides a relaxed environment for all abilities.”

— Tim D

“10/10 would exercise again”

 — Daniel S

“Great workout lovely gentle instructor.”

— Chris K

“Tim's classes are a great mix of strength and cardio, which has directly improved my running! I enjoy running but struggled to run consistently and maintain stamina until the end of my 5k. Since taking Tim's group training sessions, my 5k time has dropped from 27 minutes to 24 minutes, and my pace is much more consistent. Really really helpful stuff, and a great atmosphere to train in!”

— Rebecca L

“My husband and I have been doing strength training with Tim with the goal of gaining skills to age well. :)
Tim's training, experience and ethos have been hugely beneficial. We know we are in safe and skilled hands. It’s an investment we are really glad to have made. Thanks Tim!!”

— Bonnie H — We love the way Bonnie and her husband are taking ownership of their longterm health and wellbeing, and applying themselves to the process of becoming ‘ordinary athletes’!

“Do yourself a massive favour and join Extension Fitness!
If you’re looking for something affordable, challenging, non-pretentious, friendly, encouraging and doable, EF is the vibe.
Tim is a great person (and Deb too!) and a great instructor who knows his stuff and can explain it simply to you. The sessions are incredibly well planned and varied. You’ll be pushed and you’ll grow beyond what you thought you could do and you’ll feel great for it.

I’ve since moved overseas but miss going to sessions! I joined running, bodyweight and fitness boxing and loved it. I wanted to stay active, feel good, get stronger, have less injuries and make friends (bonding through group suffering!) It helped my surfing and improved my Park Run times too. I still remember and practice lots of the things I learnt at EF. If I was back in Perth, I’d still be going!”

— Kenton G — Now living overseas, but one of the first people to experience the ‘ordinary athletes’ difference when Tim first began coaching free sessions in the park several years before launching Extension Fitness.

“Tim from extension fitness is an expert in the field. Tim’s helped me immensely with my running and given me a custom plan to improve my running that’s achievable and most importantly keep me injury free. I would highly recommend. Thanks Tim”

— Lisa D — hospital worker, learning to build strength and balance a training program that prioritises being able to run comfortably over the long term, without losing sight of short term performance goals.

“As someone who’s never set foot in a gym, the idea that a HIIT/boxing class could become a highlight of my week would have seemed laughable to me before training with Tim. His measured, encouraging approach is clearly rooted in extensive technical knowledge and he promotes such a positive vibe for people of all abilities. Lots of fun, no P.E. trauma flashbacks. Thanks Tim!”

— Megan L — young mum with a history of back pain, getting stronger and fitter for the demands of everyday life; reluctantly learning to love huffing, puffing and getting tuff!

“Wholistic, personable service that makes for real progress in fitness/health needs.
I utilised the run assessment and one on one work to help address injuries that held me back for over a year. Previously loving distance running I was feeling very frustrated. I had accessed help from a few Physio's/trainers but things didn't resolve. I got so much out of working with Tim to find the 'why' of the issue and take action that both builds long term strength and immediately addresses the problem. I would not have considered a personal trainer previously, but Tim's service has been reasonably priced with a tailored plan to get the most from my budget, with individualised input. I had some problems trying to apply the program and he was available to help troubleshoot and adjust things without extra cost. I was grateful for Tim's work to understand and coach through the mental aspects and concerns, this made it genuinely personal training not a one size fits all program. Well worth the investment for me.”

— Rach W — mother of three young children, strategically using Extension Fitness services to get stronger and keep exercising for the long haul.

“Tim is very knowledgeable and supportive of your personal fitness goals. His classes are well run, fun and encourage a team environment. Extension fitness makes the idea of exercise a joy!”

— Stacey D. — paramedic and mother of two littlies, Stace loves the opportunity to push herself without having to expend precious mental energy deciding what to do!

“I've been going to Tim's HPGT (huff puff, get tough) classes for about a year now so a review is definitely overdue. These classes have been perfect for me. I'm weary but not annihilated at the end and Tim tries really hard to make sure everyone is working hard but staying within their limits and keeping good technique.
Unlike some other exercise groups I've been to the vibe is great. People bring their kids along and sometimes run off during a set to retrieve a toddler or two. I definitely feel like this is a class I can keep going to long term and would happily recommend it to anyone.”

— Ian P. — office worker with a young baby at home (and a brilliant dry humour at class), using our Group Training for general health and fitness.

“An interesting and different set of exercises every week makes it easy to work hard. Just one class a week and I am certainly stronger and tougher than I was before. Tim is an inspiring gentle leader. No yelling or whipping.”

— Stephen R. — hospital physician with a gift for endurance, a wry smile, and wizard-like abilities at lighting fires and navigating bush trails. When Stephen says our classes are interesting, we consider it high praise!

“I have been attending the HPGT class for a while now. Tim creates a very welcoming atmosphere and is good at catering to different fitness levels. I also appreciate his focus on making fitness accessible and easy to maintain as a life habit. Highly recommended :)”

— Malcolm P. — wearer of 80s sweat bands; not someone who likes to exercise, Malcolm nonetheless keeps coming back for more. When we say “we construct ordinary athletes”, we really do mean it!

“Tim is a great coach whether you’re starting out, or a pro.
I initially did some one on one lessons as I’m quite new and wanted to learn correct techniques and form. Tim was very good at teaching at a level I could understand, and explaining the science behind it all. He was able to understand my ability and past injuries and structure the workouts and exercises accordingly. Recently I started some of the group classes and it’s been great getting a solid workout whilst having fun.
I highly recommend Tim.”

— Geethaka F — father of 2 young kids and keen recreational road cyclist. Using Extension Fitness as a supplement to his riding and for weight management

“Tim has the perfect balance of meeting people where they are with their fitness and also pushing them to improve. He has a calm and friendly approach.”

— Jenna S. — one of our most consistent and competitive Group Training participants, Jenna is proof that while our classes are accessible to beginners and ordinary, not-yet-fit people, they still give the very fit folks a chance to push themselves!

“Great experience with the running assessment - really helpful to watch video footage of my running and for Tim to do a technical breakdown of my running form, explaining clearly what I was doing well, how I could improve and the rationale behind it. He also taught me drills and exercises I can do to help with strength and technique. With some practice I definitely feel more comfortable running, which has allowed me to up my km’s, and I’m starting to get faster too. Tim is a friendly, professional and knowledgeable coach, and I’d recommend this assessment to anyone who runs.”

— Steph W — keen recreational triathlete. She used our running technique assessment service to dial in some form changes which, along with consistent and smart training, has seen her times improve substantially

“Extension Fitness ran our much needed preseason fitness session. Tim did an amazing job at catered for varying levels of fitness, variety of equipment each week and friendly atmosphere. I am not normally a "boot camp" person but will definitely be back for more. Thanks Tim!”

— Jenny R - member of Modernians hockey club who benefitted from the pre-season bootcamps we ran for “Mods”

“Tim ran four preseason training sessions for our teams. Every session was challenging and different. His deep knowledge of physio and gentle encouragement to push ourselves produced great results for me. I was surprised by how much I was able to extend myself week on week. I'm looking forward to doing more training with Tim and Extension Fitness.”

— Phil S - member of Modernians hockey club who benefitted from the pre-season bootcamps we ran for “Mods”. Phil also attends our run club to improve his on-field fitness and to support motorcross fitness.

“Tim is an excellent coach and guide for the Wednesday morning run club I attend. He has expertise in running technique and he sets appropriate goals for everyone who attends, whether its tempo runs, intervals, or otherwise. Highly recommend.”

— David S. — long-term recreational runner, gaining strength and knocking down the parkrun PBs.

“Loving my first week with Extension Fitness. Did group classes Monday and Friday and the running club on Wednesday. Really enjoyed all classes and so thrilled to run a lap around Lake Monger. Tim is excellent. The sessions are well thought out and can be adapted to all levels. Tim gives options depending upon where you are at fitness and ability wise. Can highly recommend Extension Fitness!”

— Danielle D. — busy ICU nurse and Mum of 4 kids. Rapidly whittling down her Parkrun time

— Caroline B — Maylands local. Using Extension Fitness for physical and mental wellbeing, including weight management

“Tim has been running a pre-season boot camp which has been enjoyable and challenging. I've found him very approachable and a great instructor that certainly isn't what I'd imagine a boot camp instructor to be! The circuits have been different each week and the feedback from the group has been extremely positive! Thanks Tim!”

— Jon R. — Member of Mods Hockey Club; Jon has since done a running technique assessment and a block of PT with us to get established with a strength training regime to stay injury-free when running and playing hockey (though unfortunately we can’t help so much with the ball-induced injuries!).

“Highly recommend Extension Fitness. To have a highly qualified physiotherapist providing guidance around health and fitness is a pretty unique and special type of service. Tim is down to earth, genuinely encouraging and puts a heap of effort into designing a relevant program for each client.”

— Greg C. — using our private coaching/PT services to master basic barbell training, and a custom program to guide his progression, Greg is taking charge of his health and fitness as he moves into mid-life, with two young kids and a business to run.
NB: While Tim is not currently a practicing Physio, having that education and experience behind him is a great help in providing sensible and personalised guidance in training our clients.

“The running technique session with Tim was great. It helped me understand my current form and where I can improve. I've put into practice a couple of Tim's suggestions which have already greatly improved my running efficiency and I will continue referring back to the notes he sent after our session to keep improving my form.”

— Bethany C. — mother of a young bub, with a part-time office job; used our running assessment services to establish a sustainable and comfortable running commute.

“Tim's classes are a great mix of strength and cardio, which has directly improved my running! I enjoy running but struggled to run consistently and maintain stamina until the end of my 5k. Since taking Tim's group training sessions, my 5k time has dropped from 27 minutes to 24 minutes, and my pace is much more consistent. Really really helpful stuff, and a great atmosphere to train in!”

— Bek L. — student, gardener and avid parkrunner, Bek is one of our longest-standing Group Training clients and has been consistently knocking down the parkrun PBs and staying injury-free.

“Tim has been great at pushing myself and my teenage daughter to increase our fitness...but it has been so enjoyable that we have hardly noticed. A lovely relaxed vibe that includes people like me who are a bit more "senior" and also the fitter athlete. I have appreciated Tim's experience....I used to think that running technique could not be coached but he has improved mine. I have found that improved core strength has resulted in less fatigue during the work day and better running endurance.”

— Johan M. — dedicated father of three, on his feet a lot in a demanding medical field; a seasoned recreational runner, already experiencing the multi-faceted benefits of improved strength from just a few short months at our Group Training.

“Extension Fitness is brilliant! Tim is an outstanding trainer—gentle and generous, but professional and knows how to push you to do your best. I take my son to the group sessions with me and it's an amazing environment for multi-generational fitness. Highly recommended.”

— Rory S. — hard-working father of four; getting fit in mid-life to set a good example for his kids and live strong for the long term.

“I love the group fitness classes that Tim runs. They're a good mix of cardio and strength and every week he mixes it up. Lots of fun and a great workout. I've also had a 1-on-1 class with Tim to improve my running technique, which helped tremendously! Tim has really thought about form and structured our session really effectively. Good support and follow up as well. Highly recommend!”

— Jasmine L. — already loved exercising but comes along to our Group Training for the fun factor and added variety; also used our Running Technique Assessment to give shin splints the flick and make running a comfortable part of her fitness regime.

“Daily exercise makes a huge difference to how I experience the world but I don’t want to make decisions about ‘what’ and ‘how’ after a long work day. Extension Fitness sessions balance exertion with care and Tim’s thoughtful programming means you just have to show up and get going. I’d highly recommend Extension Fitness to anyone looking to get fit, keep fit or push themselves harder.”

— Robbie L. — works in a demanding office-and-people job; keeps sane with regular doses of strenuous exercise, and squeezes every last drop out of our Group Training.

“I've tried gym-ing before but never felt that interested or satisfied, but after spending time with Tim I really started to get results and confidence. Now I feel much stronger and fitter which has been fantastic for everyday life and I know will help keep me healthy in the future. Tim knows his stuff!”

— Felix S. — strength training with a group of mates and discovering the joys of watching the numbers go up!

“Tim helped me wonderfully by strength training my weak areas - Especially my back where I’ve had injuries. He is very personable and able to relate to beginners well. Not at all the intimidating environment you can sometimes encounter in a gym.”

— Scott S. — A seasoned recreational endurance athlete, experiencing the benefits of strength training and always eager to encourage others in their fitness journey.

“I've tried to keep fit over the years with rowing and bodyweight workouts, but running always defeated me. Even going for short runs I felt uncomfortable, inefficient, and would pull up sore the next day. I had two sessions with Tim where he observed me running and guided me through different techniques. While Tim was great at demonstrating good running form and talking me through it, I found the most helpful thing was his ability to convey a sense of what I should be feeling when running. Since seeing Tim, I've been running with a backpack on my commute 3 times per week for 8 months. I used to hate running. I now look forward to finishing my day in the office so I can run home. I feel comfortable running, don't pull up sore, and am injury free. Thanks Tim!”

— Nathan C. — new dad, office worker; fitting exercise into the nooks and crannies of family life.

“I came across Extension Fitness when my wife started boxing classes with them. I noticed they held a running class straight after so I decided to give them a go for a couple of weeks as I had just started running. My only experience with running was doing the ‘Couch to 5k’ app, which - while it got me running 5km - didn’t teach me anything about how to run. With Tim’s patient assistance I was able to learn about how to improve on my running technique, strength and fitness, and how to stay injury-free. Tim took a lot of time explaining each step and why it mattered in the short and long term as someone new to running in their mid-30s. Worth every cent!”

— Frankie L. — professional muso and new dad; keeping physically and mentally fit with a combination of running and cycling.

“I’ve been on a journey of restoration. I’ve had post-injury issues and chronic back pain for 14 years. I’ve been trying and re-trying to make a reentry in strength training over this time. Working with Tim has been tremendously encouraging. He has shared information with me specific to my scenario, which has shaped how I consider pain and its management. As a result my confidence has solidified and at last I’m tracking forward with consistent sessions, growing my strength and posture with an overall sense of improved wellbeing. On the weights, Tim’s coaching skills stand out in the manner in which he encourages people to improve and maintain good form. Tim has helped me to identify and stick to weight limits to ensure injury free progress. His technique is excellent and I find it helpful when he demonstrates as it helps me visualise what I need to achieve. The atmosphere is the best and I really enjoy watching others thrive here too. Thanks Tim!”

— Andrew I. — training alongside a supportive group of guys; empowered to move beyond the “bad back” narrative, building movement strength and movement skill.

“Tim has helped me develop my deadlifting technique and I have seen considerable improvement in my ability to lift heavier weights while feeling less at risk of injury. He gives his advice without needing to assume an 'aggressive' character, which makes his coaching friendly and enjoyable.”

— Jonty K. — already motivated to workout and keep fit, Jonty has enjoyed taking his strength training to the next level with some expert guidance and group comaraderie.

“Tim was great. He helped me work on some long term technique issues in my running and gave me a clear path forward on addressing it.”

— Paul Y. — a sportsman earlier in life, now regaining fitness as a father of two; wanted to address nagging technique problems in order to build endurance and open up the time-efficient option of running, to maintain health and fitness for the long term.
