I've had such an amazing experience with Giuseppe who has been my PT for nearly 12 weeks now. He has been there 24/7 for me, whether that be for advise or general questions i needed asking. The transformation so far has not only changed my physically, but mentally too. I cant thank him enough. Would highly recommend.

I cannot recommend James, Giuseppe and the rest of the BTX team highly enough. They are an incredible team that have gone above and beyond to support me on my fitness journey with them. I undertook the 12 week Kaizen Warrior transformation as an online client and got into the best shape of my life at age 47, dropping to just over 5% body fat and adding 2 kg of muscle. If you’re serious about getting into shape look no further than James and the BTX team!

Hi, started with the BTX guys 5 months ago and have lost 17kgs in bodyweight while also putting on some muscle. Very happy with the team and found the weekly check ins / accountability gave me the extra push I need to stick with the plan. Overall good experience and would recommend to others. John Timlin.

I've worked with both James and Giuseppe over the last four years. I would highly recommend both as online or in person trainers. They cut through the noise with their mentoring and advice in terms of both diet and nutrition. Have achieved significant improvements in both my training, physique and health. Great guys to work with - if you want to improve - stop wasting your time and call them.

BTX is without doubt the BEST gym experience. Ever! From onboarding to training and in every session, the team are fantastic. They are highly organised, sincerely dedicated, super friendly but most importantly they are knowledgeable and experienced. Big up to Eva for getting me signed up so easily and to Syzmon for taking me on this incredible journey of self development.

I’ve been training with BTX and the team for about the last 6 months now, and have had an excellent experience with the team there. From the amazing nutrition advice provided, all the way to the coaches there, it’s been a great experience. A special shout-out to the man who’s made training actually fun, whilst also educating me on things I never would’ve learnt about - Adrian, the general of BTX! If you’re lucky enough to have the chance to train with him, take it! He’s a credit to the team and teaches you things which stick for life - not just whilst you’re at the gym for a few months!

Been going here for a few months now and all I can say is that the experience has been exceptional. The gym is perfectly located and kept in pristine condition, the staff are friendly and helpful, my workout and diet plans have been tailored specifically for me and I've seen my body fat percentage drop for the first time in years! I owe a huge deal of gratitude to my PT Simon who has been with me since day 1 and without his professionalism wouldn't be anywhere near my fitness goals as I am today. Thank you Simon and thank you BTX!

Fantastic experience so far. Great motivators with a good level of attention to detail. As someone who is used to PT I am impressed with how they manage to continue to make the experience innovative and motivating.
