10/10 recommend Jonny! I started working with Jonny after attempting a few marathons on my own, realising I definitely needed some guidance and support. Jonny did just that and more. He was open and honest with his coaching style and mentoring, he always listened to any of my thoughts, ideas and hopes, and provided not just running plans but also nutrition and lifestyle support. With my shift work, Jonny was amazing with planning runs and other workouts taking this into account, as well as motivating me to stay consistent. With Jonny I was able to take half an hour off my marathon time! He is such a motivating coach and such an inspiration. More...

Very sweet and kind words Alana, thank you. What you have experienced (for example in the 'World Major' London and Sydney Marathons) and the MASSIVE IMPROVEMENT in knocking 30 mins off an already good marathon time is testament to your hard word and dedication.

I went looking for some coaching to improve my running, I found Jon (Peak Performance) who has been great. His coaching has helped me achieve PBs in distances from 5k through to 30k. His guidance through injuries has been essential in my recovery. Additionally, he has supported me during challenging times in other aspects of my life. A highlight was meeting up and running together in last year's City2Surf 😊 More...

Thank you so much Suse. I'm so grateful we got to run the City2surf together (my favourite race in Australia) last year and excited for the next life changes you are doing now. Plus all the races you have lined up for the rest of this year and next

Jon was amazing at keeping me motivated and showing up to get results. He’s there to tailor to your level but keep you improving

Thank you so much Bryan. When you have your determination to go harder and push more each session, HIGH QUALITY RESULTS, are the only outcome!

I started working with Jonny because I needed a change in my life both physically and mentally. Since then, I’ve noticed a change in my mindset about diet and fitness. I’d recommend Jonny because he's always there to provide motivation and knowledge. More...

Thank you for these great words Preet. Your mindset, consistency and strength levels have come on leaps and bounds. Am looking forward to the next stage of putting on both mind and physical MUSCLE!

Back in 2024 I failed The 96km Kokoda Challenge, I had to DNF due to a knee and ankle injury, but I made a commitment I would complete Kokoda in 2025.
6 months went by with little to no progress, so I decided to leave my ego at the door and invest in a coach and that was the single best choice I could have made and I genuinely dont think I would have been able to do it without Jonny.
He pushed me physically as well as mentally, he gave me the accountability and the confidence to hike 50km 6 weeks out from kokoda which gave me a huge amount of confidence and during the last 6 weeks we levelled up again.
I not only completed The 96km Kokoda Challenge, I finished stronger than I ever thought possible
Now we are working towards my first solo 50km ultra run!
Keen to keep kicking goals 💪🏻✅️ More...

Having a DNF in 2024 and then SUCCESSFULLY completing the 96km Kokoda challenge in 2025, showed PHENOMENAL determination, a never give in attitude and OUTSTANDING physical + mental conditioning! This has definitely set you up to be SUCCESSFUL in you next exciting adventures (both in life and trail races)

I started working with Jonny about 2 yrs ago. I wanted to seek professional guidance in my running endurance training - in particular the marathon distance.

Since then, Jonny has guided and trained me through some serious World Abbott Majors like Tokyo, Berlin, London and Chicago marathons and even rugged trails like Mt Kosciuszko.

His personalised training plans are flexible and covers all aspects needed to succeed (just like the elites). From nutrition, strength training, recovery and learning how to have a positive and successful mindset. He looks at the WHOLE picture and breaks it down into more manageable segments.

I 100% recommend Jonny to anyone who wants professional guidance. He is a caring and respectful coach. He has a wealth of knowledge and is always available for any burning questions I may have (even if I have asked it many times before). More...

WOW, what can i say Kim.... 2 years already. Such amazing words here , THANK YOU so much. My favourite thing as a coach is being able to pivot and answer ANY questions you have on all these topics. AM SO PROUD of all the World Abbott Majors like Tokyo, Berlin, London and Chicago marathons and your trails like Mt Kosciuszko, and remember Sydney is now on that fantastic list too! Getting your latest LIFELONG P.B in the Chicago Marathon was so so DESERVED, after such superb conditioning all year long. Am so excited for all your exciting events planned for 2026 and being a part of you journey as you coach, is an absolute pleasure and INSPIRATION for so many of our community group!

I started working with Johnny because I had signed up for a 32K Trail ultramarathon with only casual running experience. He tailored plans around my lifestyle never overloading me, with constant feedback and advice and I ran my ultra within my goal. Can recommend Johnny enough. Top man. More...

Francis, you did ABSOLUTELY INCREDIBLE in that 32km trail race. Hitting the training EXTRA HARD with all the speed work, stairs, hills and trails i recommended and going above and beyong with the necessary RECOVERY work required with all that... Plenty of painful blisters and moments through it all... Hitting PB's EVERY MONTH and am truly looking forrward to the next 50km trail challenge (plus your other exciting sporting adventures too)

I signed up to work with Jonny because at the age of 52, I was struggling to lose fat and change my shape even though I was exercising regularly. I found I was injuring myself regularly and was constantly fatigued and dissatisfied with the way I looked. Jonny gathered extensive information from myself and my physio to create a workout regime that supported my physical limitations at the time, while still creating a routine that offered challenge where I wanted it.
Within 3 months, I was seeing a dramatic change in my body. I had lost a large about of body fat and could see definition in places I hadn’t been defined in years. Like my abs and my arms. Jonny is encouraging, supportive and challenging if you want it. His overwhelming message is safety. My body is stronger than it’s been in years, I’m proud and more confident than I’ve been in years. The impact Jonny’s training and supportive advice has had on my mental health as a result, is something I struggle to put into words. I am truely forever grateful. I have and will continue to recommend Jonny to anyone needing support in their exercise journey, or those already fit/healthy, wanting to step things up a notch. Jonny’s approach to wellbeing is very holistic and I truely believe he can provide benefit to anyone who reaches out. 5star training, advice and support. More...

Bec, i am truly grateful for your words here too, THANK YOU. To help you SUCCESSFULLY manage your injuries, gain body shape, confidence and self belief, is truly rewarding. You are improving your strength with PB's EVERY SINGLE week, HAVE SUCCESSFULY completed a 10km race and i can say with all my heart and soul, that your food intake has so many IMPRESSIVE 9/10 and 10/10 days, there is such an exciting OPPORTUNITY for IMPROVED mental health, physical health and longevity, as we move towards the next goals we are now setting early for next year. The key to SUCCESS is consistency, communication and i admire you; 'never being satisfied'. It's a WINNER'S mentality and one i admire IMMENSELY!

Working with Jonny has been one of the best decisions I’ve ever made. He hasn’t just been my run coach, he’s also been a fitness and life coach, guiding me through some of the toughest and most rewarding challenges I’ve faced.

Jonny supported me through rehab for Chondromalacia Patellae, and with his help I was able to bounce back stronger than ever. Just two weeks after being cleared, I ran my first marathon and two weeks after that, my first ultra (Bondi to Manly 80km). Since then, he’s coached me through my first Half Ironman (Western Sydney 70.3) and my first Backyard Ultra in St Ives, where I managed 137km.

What stands out most about Jonny is his versatility and his ability to keep me accountable, motivated, and confident, all while helping me stay injury-free. He truly believes in his athletes, and that belief has pushed me to achieve things I never thought possible.

If you’re looking for a coach who will not only get you to your goals but help you go beyond them, I can’t recommend Jonny highly enough.

The proof’s on Strava. More...

Tyron. i hear all the time by 'experts' and specialists' that someone shouldn't and never will, run again. Testament to your DETERMINATION + CHARACTER, that you didn't listen and that in the last couple of years, have SUCCESSFULLY done everything from a single marathon to that double (80km) marathon and the overnight 137km backyard ultra. I TRULY appreciate these kind words and that even though, i want to just coach + chat about running, that you take on, listen and apply, ALL of the injury management of your knee and body overall! YOUR MINDSET and WORK ETHIC when in a race ZONE is truly impressive and living breathing PROOF that with the right mindset and TEAM, ANYTHING is possible! ANYONE with an 'injury' should take INSPIRATION from what you have acheived and CONTINUE to achieve (including an exciting 100km this month).

I’ve never had a personal trainer before, and working with Jonny has been an incredible experience. The results so far have been amazing, and I can honestly say it’s been a game-changer for me. What really stands out is the way Jonny takes the time to adapt training and food plans to my lifestyle, making them both realistic and effective. He pushes me to achieve my goals while making sure everything feels sustainable and tailored to me. Jonny’s dedication and support make a huge difference, I couldn’t recommend him highly enough!

Pablo, THANK YOU so much for this recommendation. YOU have already achieved such an ELITE body level and every single challenge i set you, you take it on with admirable effort. Whenever there is a moment of plateau, i'm so GRATEFUL, you go on to a whole new level or change i recommend (especially with your food intake) and for that, i am so EXCITED for a LIMITLESS level for what you can ACHIEVE, for the short and long term

Working with peak performance has been an amazing experience… I lost 14 kg! I ran a half marathon in 1 hours 43 mins and I improved my 10km to sub 47 mins and my 5km to 23:18 mins …. Thank you peak performance for the life changing experience! I can’t wait for what is coming next 🙏 More...

Spyros, what can i say.. 14 kg of weight loss is a TREMENDOUS achievement in itself...... The FACT that you have gone even faster in your 5km and 10km times, in the few weeks since you wrote this, is TESTAMENT to your work ethic and DRIVE! As you have experienced, there are 'bumps' in the road when training to this ELITE level. You have overcome all of these and literally come back FASTER + STRONGER! What a STRONG MINDSET you have and i love the mindset coaching we do! I can honestly say that due to this, i believe that each month and year, you are going to go on to levels, that as your coach, i find extremely exciting!

Jonny is not just an amazing coach, he is an all round great human being. He takes a wholistic approach to coaching as he understands that achieving goals does not come just from the physical aspect. It encompasses the mental and emotional too. I have achieved so much since Jonny has been my coach. I recently completed the Sydney Marathon, ticking off a bucket list goal. He gave me support and inspiration along the way and was right there to congratulate me at the end. I’ve also hit a PB of 90kg deadlift which has eluded me for some time. His dedication is unwavering and he has a genuine desire to help others be the best they can be. He is my trainer, my life coach, my mentor and my friend. 🙏❤️ More...

I have worked with Jon since the start of 2025 and he has helped me transform my life and reach fitness goals well beyond what I thought possible. He is knowledgeable and thoughtful in his approach and never fails to acknowledge wins along the way. He has also helped me with health goals and I'm on track to reach a year of alcohol free. I would recommend Jon to anyone looking for a coach to make lasting change More...

When I started with Jonny I was overweight and unfit. I had started running but was constantly injured.
Since we started working together he has taught me a lot of lessons with diet and nutrition which has changed my life as I am more energetic, more motivated. He has been able to tailor the exercise plans to my needs and wants out of it. I’ve been able to stay injury free but also become a lot fitter and healthier. And I have a new appreciation for fitness and health.
I’d definitely recommend Jonny to anyone that is even thinking about getting on a journey whether that’s fitness, weight loss or anything else they need. He is on point and has a passion for it which makes it a lot easier to follow. More...

Jonny is on point and really knows his stuff. I couldn’t be happier with the progress with my running and especially the weigh loss to start with

I started working with Jonny because he’s got the experience under his belt in mentoring and coaching individuals of all backgrounds to achieve their goals, he also demonstrated to me personally that he’s 110% committed in seeing improvement and success. Jonny takes the time out of his day to regularly check in to see how everything is going which I found helpful and very easy to communicate.
Working with Jonny I noticed a significant change in my fitness as he knew the structure and plan to give me to reach my specific goals for races etc.
I’d recommend Jonny to anyone serious about their goals whether it be running, lifting, or even walking. To summarise, we need more people in the world like Jonny who imposes such a positive energy and commits 100% to you as an individual. More...

My life health wise has totally turned around. My vege intake has doubled and my general daily protein intake has quadrupled! I don't need to log my foods anymore for this to happen. I have managed to keep off 3-4 kg without having to log in foods as well. Jon is a lovely person and I felt safe working with him. More...

Peak Performance Coaching is more than coaching — it’s genuine care.

He takes into consideration life and all the curveballs it throws at you, never making you feel like you’ve failed. Instead, he adapts and encourages, always putting your health and wellbeing first.

It’s clear he genuinely cares about each client, going above and beyond to support not only your performance goals but also your overall quality of life. That balance of accountability and compassion makes all the difference.

If you want someone who truly invests in both your progress and your wellbeing, this is the coach you need. More...

Johnny is fantastic. He takes the time to understand your needs and has a huge amount of experience to meet you where you are at and design programs for your ability and equipment. Super easy to work with, extremely responsive to messages and calls, I can see myself working with Jonny for a long time More...

It's been great working with Jon every day for the past 18 months. He gives me the encouragement I need with my weight loss; muscle building; life coaching; and pretty well anything I need.

I strongly recommend getting Peak Performance Coaching on your team to succeed with your health and well-being goals. Thanks Jon, you've changed my life. One mindset at a time. Love your work. More...

I started working with Jonny because I was struggling with depression, anxiety, and weight gain, and I wasn’t happy with how I felt in my body.

Working with Jonny, I noticed incredible changes — I lost 10kg in a short time, learned about nutrition, no longer struggle with mental health issues thanks to his holistic coaching approach, and even saw my abs for the first time in my life.

I’d recommend Jonny because his coaching goes far beyond the gym. He helps you shift your mindset, build healthier habits, and live a lifestyle where feeling great and looking good become natural by-products. More...

Peak Performance Coaching, put simply, was the difference between me achieving my fitness goal and not achieving it. I’d tried individually to train & run 5km in sub 20 minute time for 12 months and failed. I engaged Peak Performance Fitness & approximately 5 months later, I ran my first ever sub 20 5km run, coming in at 19:52. Thank you Jon Cainer! More...

I started working with Jonny because I was training for a half marathon.
Working with Jonny, I beat my previous pb by 2 minutes and gained a deeper understanding with optimal training and recovery.
I’d recommend Jonny because he has a lot of knowledge, experience, and provides lots of motivation and encouragement especially during training slumps. More...

I started working with Jonny because I needed help organising the best way to organize my nutrition and exercise.

Working with Jonny, I noticed that he was always available and always eager to help me in any way I needed.

I’d recommend Jonny because he is a very skilled and knowledgeable Trainer who is really on your side and genuinely cares about you and your success. More...

Peak performance is a great example of a personal trainer who’s committed and dedicated to his clients, and provides a really good base to work from and do better.

I used John at Peak Performance when I was struggling with my weight and metabolism as an aging man. He listened and helped with a system for me. Always there to encourage and motivate and hold me accountable.
Definitely give him a try. You won’t regret. More...

I started working with Jonny because I wanted to lose weight.

He listened to me to understand what I wanted to achieve and came up with a plan for everything we would be doing over the weeks and months.

Given his professionalism, I immediately felt confident and relaxed, and the results spoke for themselves. I reached my weight loss goals, while being fitter than I'd ever been before.

I continue to train with Jonny now and continue to feel fit and strong. I highly recommend him. More...

Jonny has been training me for years. He’s extremely knowledgable and very professional.

I started working with him because I wanted to get fitter and stronger. He sets goals and targets for me, and always explaines everything and why we’re doing what we’re doing.

Training with Jonny has allowed me to get to a level where I can now lift much more than I ever expected too, while I feel like I can just run and run.

Jonny continues to challenge me and I continue to feel very confident in his training. I highly recommend him. More...

I started working with Jonny because I wanted to be able to run the bridge to Brisbane without embarrassing myself and without dying.

Working with Jonny, helped me reach my goal and even though a few times I cracked the pads and wanted to give up he helped me through it without belittling me or making me feel bad for it.
He helped not just with running but food suggestions and different perspectives. More...

Jonny was great, got me out of a big fat slump of laziness and back to what I should have been doing: good Exersise, good results and keeping trimmer (than was)!

Started working with Johnny with the aim of running longer and stronger - to run a marathon.

Working with Johnny, I was able to run further and faster - and learnt a lot about how to prepare well for running.

Strongly recommending Johnny because we hit our goal - with his coaching and guidance I got through that marathon!!! More...

Jon was a super amazing coach and was the rock i needed during training for a marathon. He has so much knowledge not just about what it takes to physically achieve in running, but how to keep your mental strong and recovery high.

Jon was so accomodating and whenever i had any doubts he would always be so responsive on messages whenever i needed guidance on something in our training program.

He cares so so much about driving you to success and is very present. If you need a coach that will always be available and checking in with you then Jon is the best choice. From my experience with other coaches, some are just so busy that they are only able to check in very rarely, Jon is so present, responsive and always around to help.

Although iv been through tough injuries in the past that hindered my progress, Jon was always there to support me through the mental aspect and keep me positive. Marathon training is very tough on your mental and its important to have a coach that can accomdate to that aswell.

He also helped me greatly with my nutrition, he really is a coach that can support you through all aspects of training (programming, mental support, nutrition, recovery, accountability, he really does it all and takes the guess work out for you)

Overall an amazing experience with Jon as my coach would highly recommend. More...

I started working with Jonny initially for weight loss. I never considered myself “unfit” but since working with Johnny I’ve not only started to run for the first time in my adult life (at 47! !) but I’ve set targets like running the base of Uluru, and achieved those targets.

Through Jonny’s careful crafting of workout plans, nutrition guides and tracking of food, I am now a regular, 4 or 5 day a week gym goer, I walk/run between 12,000 and 20,000 steps per day and, in line with my original goal, I’m down from 111kg to 84kg since April 2024.

All of these achievements are incredible, but I’d recommend Jonny because of his holistic approach to health and wellbeing. My physical health is the best and weight is the lowest it’s been in my adult life, but my mental health is also vastly improved, not only do I think more clearly and make smarter decisions when I’m exercising, but my years-long struggles with anxiety and depression are in the past. I sleep better, I think better, I feel better overall and this is because Jonny helped me see that physical and mental fitness are inextricably linked.

I cannot recommend Jonny highly enough! More...

I started working with Jonny because I had a daughter and was to focused on my company and wanted to find a better work/life/fitness balance.

Since then, I’ve noticed a huge change in my life. It’s great having his constant support and constant positive attitude always giving me great words of wisdom. It’s really helped me continue to progress even with such a busy life. More...

I cannot recommend Jonny enough! He is incredibly professional and created a gym routine specifically designed to improve my strength and mobility for pole dancing, as well as to help me start running. He tailored everything to suit my lifestyle and work schedule, and even provided workouts I could do at home along with general guidance and support. His services are perfect for anyone starting their fitness journey or looking to take their training to the next level. More...

Jonny’s an excellent mentor. Super down to earth and will always go the extra mile for you. Highly highly highly recommend him to anyone looking for this type of service 👍

Jon is a fantastic trainer and health coach. He customised my diet and workout plans to suit my needs, while still focused on the goals. The workout plans were in particular were very impressive as I only wanted to use the cheap equipment that I have at home and focus more body weight excersizes. I saw impressive results in the short term. Also Jon is very interactive, communicative, diligent and encouraging. I totally recommend Jon as a complete health coach. 5 stars More...

I've tried gyms and diets for the last 20 years and nothing seemed to stick. Peak Performance changed all that. Jonny went above and beyond to educate me and help me make changes for life. My biggest requirement was that it had to be sustainable, I wanted to still have a beer or some chocolate sometimes! Jonny's approach helped me work in healthy eating habits and realistic exercise into my life with minimal adjustment.
Flexible programs are a massive draw card too. Often, trainers will have 1 price and 1 program. Peak Performance were really flexible in their approach and offering.
Strongly recommend for anyone who is flat out balancing work and family life! More...

so far, so good. Jonny seems to understand what I am needing.

He is personable and genuinely cares. He makes you believe in yourself

I have been working with Jonny from Peak Performance Coaching for the past 6 months, I cannot recommend highly enough, Jonny goes above and beyond to try and benefit me, he’s so passionate about his career and benefiting others. I have learnt so much in a small amount of time and can’t wait to see what the future holds with such a professional coach guiding me in the right direction. More...

This trainer is beyond amazing. The best I would give him is REAL and result driven. He cares about his clients and is with you 7 days a week. I’m a parent with shift working hubs and he caters for all injuries, he has got me through harmful injuries and mental hardship issues and broken plateaus and I’ve lost an amazing amount of weight that no other trainer has done. He’s a parent himself and knows all the ups and downs that come with the kiddos. I am still on this journey and will be a long term client as he has considerably changed my life. Thank you so much matey, you’re a legend, More...
