I had an awesome time with Jason.
He taught me the fundamentals of boxing and kickboxing. I was able to have fun and learn while sweating my ass off. We identified my weaknesses and what to work on and I enjoyed the different challenges. Jason has helped me with my confidence and improved my skills. I do see a difference in my abilities. I feel more confident to give myself new goals in life that otherwise I wouldn't of considered. It's been encouraging training with Jason. I'll miss the chats and the sparring sessions. Thanks Jason

Firstly, I want to start by saying that you are a great PT and thank you so so much for all your patience, professionalism, and hard work.
The past 2 months have been life-changing; after having my ACL/ meniscus surgery on my left knee my fitness really went downhill.
You took all my concerns and goals onboard from day one, guided me throughout my fitness journey through open discussions about introducing changes to my meals and following a meal plan, staying consistent in and out the gym and setting myself weekly goals to realistically achieve results.
Thank you for pushing me when I was lacking motivation, pushing me to finish every set, and for making each session super hard but fun!
I cannot thank you enough!
I'll be back

Jason thank you so much for all the work, especially the very fast counting between sets, my overall training has completely changed and along with the lifetime friendship I have acquired some amazing new routines and techniques. Has been a painful pleasure and look forward to more sessions

Over the years I have tried so many different gyms, trainers but after about 1-2 weeks I would fall off because I would either loose interest or just get bored easy. When I started training with Jason earlier this year I got motivated again, gained back my confidence and started actually enjoy going to the gym. He has taught me a a lot and also guided me on the right things I should eat. Jason is really easy to get on with and genuinely cares about his clients. Just after a few weeks I started seeing results and noticed I am getting much stronger and toned.
My fitness level is probably the best it has ever been and it's all thanks to Jason. I would strongly recommend Jason to anyone that is looking to get in shape.

Jason, thanks for the last 3 months! I never knew I could do gym at 6am twice a week and here I am. Thanks for always motivating me and pushing me to do better. I really enjoy our sessions and the fact that you show me what l am capable of. I also never knew l'd love boxing so much! Looking forward to smashing it in our next session!

Just wanted to say thank you! After 2.5 months working out with your guidance and help I can definitely say I feel much stronger, leaner and happier with my lifestyle.
Lost more than 4kgs and cms and I'm really looking forward to continuing working together to achieve more amazing results!
I must admit I couldn't have gotten here without your positive attitude and the fact that you always ask for one more rep, heavier sets and tougher challenges.
Thanks!

Hey Jason,
It was brilliant working out with you for the past two months! I was lacking structure in my workouts and you really helped with that. Thanks for pushing me to my limit too - your friendly but motivational methods made each session enjoyable.
Can't thank you enough for your support and guidance. I'll be back!

Just wanted to say huge thank you for motivating me and for always putting in so much effort. I know how much I would complain at start of each exercise but then by the end I would love it and feel so good !! Every session has been worth it only because you make workouts fun and you are so good at your job! Thanks for putting me into shape i was able to be ready and fit for my modelling work abroad. And lost 7kgs!! Which was only possible because of you! So thank you and I'm really missing our boxing sessions can't wait to get back at it b
¿ the best PT ever!!
One thing of the many that always makes me laugh is your very strict!
Your balance in having fun and discipline is crazy. I would think I could skip few reps when we are laughing at a joke but that never happens instead you make do more. so basically you're amazing at your job

I trained with Jason last year October to November and found him to be incredibly professional and personable to work with. He was patient, understanding and took note of my fitness goals. He definitely exceeded my expectations and I would recommend him to anyone who desires a focused and friendly

Loved working with you. Was really anxious to use the free weights and didn't really have any direction/strategy of how to reach my goals. You offered really constructive and easy-to-follow guidance which has made a big difference.
Cheers. I'll be back after summer

Honestly theee best PT in the game!!
Without your guideance I wouldn't be where I am in this journey. Seen a huge improvement in my weight loss, got numerous compliments and that's all down to you for constantly pushing me even when I wanted to give up and cry (which is most days)
Believe me when I say this guy will not let you give up, he will motivate you and push you even when you think you can't do it, he knows you can! And.. that's what makes him such a good PT. He will take you out of your comfort zone, keep you on track, make the sessions fun & enjoyable and he will get you the results! Always enjoy my sessions and look forward to the next. So, thank you for being so patient with me, listening to me and for just being you!

I just want to say thank you so much for the most amazing 2 months (and of course the past 2 years!) of training with you.
You really make me feel confident in making a come back to the gym and help me improve not just in my fitness but mentally too! The sessions are intense but I get such a good feeling after each one and want to come back for the next ready to improve!
I can't wait to book my next set of sessions with you!

Jason is a great personal trainer. I was 64kg when I started with Jason and today I weigh 60kg. I will recommend xtra.fit always. Jason truly cares for his clients and flexible with time. Best personal trainer ever!

Thanks Jason! I definitely wouldn't have been able to achieve this without you pushing and guiding me.
I'm so happy with the results but more so the confidence and drive training with you has given me b. It felt so daunting when I first started as my fitness was so bad and I can't believe how much you have helped me improve that in such a short amount of time. Thanks again for being so patient even when I moan!

I had sessions with Jason for about 2 years before leaving to move to Hong Kong. He's always been really flexible and supportive. His sessions were tough but as well as giving me results they were fun, varied and effective, and they taught me how to use the equipment and structure a workout by myself. He's been a PT and a friend throughout and I can't recommend him enough.
All the best for the future Jason.
Thanks for all the help and for making me fitter and healthier. I've developed long term habits that I can carry on throughout the years to come.

I started my weight loss journey in 2023 and getting in touch with Jason was the best thing. Not only is he professional, flexible with a positive attitude, he has been dedicated to help me get closer to my end goal then I would have on my own (as I would have given up by now). The sessions have been tough but he made them enjoyable (apart from the burpees), he has taken the time to switch up the sessions which improved my fitness level and gave me confidence to get back into the gym. He has helped me stay consistent and keep on track the last 16 months, something I was struggling to do.

I may be your most annoying client but a massive THANK YOU Jason for everything - keeping it 100, pushing me out of my comfort zone and getting me to where I am today, I wouldn’t have done it without your help and guidance!

If you’re thinking of getting a PT, I would highly recommend getting in touch with him, it’s been a game changer for me!

Been training with Jason for now 4 months, and I am seeing a major difference. I was complimented for my weight loss within the first month of Training! I am now having to even buy new clothes! Jason is an excellent and motivational personal trainer, i would highly recommended him to anyone who is looking for good results! Not finished until I get my six pack!

Jason is the BOSS when it comes to personal training...l've had a fair few personal trainers in my time but Jason has been the only one that I've managed to stay with for 2.5 years plus. Keep doing your thing Jason!

Just a quick message to say thank you for the past couple of months!
The sessions have been HARDD but so worth it and immensely beneficial! Your advice and your guidance has been so rewarding and I can really feel a difference! Not only physically but mentally too!! I have really fallen in love with exercising again and that's down to you! I know it doesn't seem that way because I'm constantly shouting and screaming MENTALLL at you but I know you do it for me! You have another level of confidence in me and make me do exercises I never knew I could EVER IMAGINE 6 but it all has been worth it as MENTAL as it has been! I'm looking forward to
achieving my next goal with you even though I know it will be tough but will be worth it! Thank you once again

Jeson is very friendly,easy to get on with,approachable and good at what you do.
Helped me to tone up and get fitter and stronger. Yes but still long way to go.
Emotionally: I can forget about home stuff for that hour & concentrate on me.
Physically: My body is slowly changing and I feel so much better for it and stronger.
Mentally: I can see the results and it motivates me to carry on and not stop.
Definitely recommend Jason. You’re very good at what you do, you do not make me feel stupid, and I do not feel so self-conscious when exercising next to all the “super-fit” people. If I was not training with you I know I would not go on my own because I would feel very intimidated. I also would not feel confident enough to use the machines on my own and would probably avoid them.You also care about the well-being of your clients and if there’s any injuries etc. you change program accordingly without any hesitation.
You are a valued PT. Without your help I would not be where I am today. Thank you!! Highly recommended !!

I have collaborated with Jason a couple of times now , and each time I have been impressed with the outcomes we have achieved together. Jason's approach to goal setting and achievement is systematic, and he takes the time to explain the rationale behind each step of the process. He is also open to all questions, about workouts, diet, and anything in between which is great knowlegde to keep going forward. He strikes a delicate balance between being firm and adopting a personalized approach, which gives you a sense of accomplishment after each session. Also the results that you can feel and see serve as a powerful motivator, and Jason's guidance extends well beyond the duration of our sessions.

Jason is an unbelievable mentor/trainer and more importantly a friend. He pushes you to your limit but in your own pace which I have never seen any personal trainer do (and I've had quite a few). I wanted to lose quite a bit of weight, from minute one after the consultation I knew I had the right man. I had my complete trust in him and our journey together has made me reach my goal from 87kg to 78kg. I feel so much better healthier and fitter. Could not reccomend more.
