My experience with Btx as well as with Reshma is amazing so far, having the guidance and involvement from the team at Btx is an amazing thing, I have been able to see result while training with Reshma within the first 3 weeks as she is such an amazing person as well as a experienced trainer, she pushed my limits while also taking care of my previous injuries, the diet was a bit hard at first but she was very opened to give me some tips on how to make it easier, I would say from personal experience with Btx as well as with Reshma that they are a devoted team and as long as you have the commitment and the proper support from people working the Btx team you will get where you want in terms of your goals.

I have always been able to accomplish anything I put my mind to but getting into shape has been the one obstacle I’ve always struggled with all my life until I met James Cooper at Hampstead personal training. James knows his stuff from nutrition to training and motivation. I can’t recommend him enough… Not only am I getting into the best shape of my life I’m seeing the nutritional and health benefits also. It’s the best investment I ever made. Thanks, JC for all your help!

the best in all of London. I had tried almost every diet out there and I'm relatively in shape but just struggled to stay consistent diet-wise. since I started I've noticed increases in strength, speed and my body composition is changing too. My gas tank is also so much better and I'm able to row and train in bjj for long periods of time. I'm also not shying away from foods which has helped me to stay consistent. I now look leaner but fuller at the same time. Can't recommend highly enough

BTX has really helped me to achieve sustained and effective training based on focused nutrition. Their dedication and commitment really shines through, which creates a positive and enjoyable experience. They want the results as much as you do and will work out the best route to those goals! Along with Giuseppe, James and the rest of the team I would highly recommend this camp to anyone serious about making a real change.

It is now a month since I started with Reshma. Wasn't too sure how BTX was going to help me as I have been a gym nutter for over 40 years and think I know it all! Well, I was in for a surprise, Reshma is brilliant, with small little changes to my technique, I have managed to shift 1/2 a stone in weight along with my recommended eating programme. She is incredibly knowledgeable on recipes, on eating well, on trying new products and as a vegetarian, she has helped me up my protein which I think I have suffered a deficiency of for years. Forget the days of post menopause tummy - I am heading for my six-pack - Reshma you are one amazing trainer in every sense!!

I have started a body transformation plan 3 months ago with PT Giuseppe Marchesani member of the BTX team,I must say I have never felt so good into my life! In about 3 months I lost 10Kg obtaining a great muscle definition as a first part of the program,before the bulking phase. I am very grateful to have Giuseppe as my PT: he weekly monitors my weight and definition,updating weights exercises etc. Giuseppe is very reliable and professional. He but also James and all the others from BTX know very very well what they do and how to tailor the program to each person. Highly reccomended!

I’ve been working with Giuseppe for two months now and have already achieved progress I couldn’t do in two years on my own (consider myself advanced at the gym). You need a coach who has the knowledge base to help you be as efficient with time and energy to reach your specific goal (it’s not just about going to the gym everyday). The team are friendly where you can be open with your challenges for them to really help tailor a programme for you (including weight sessions, cardio, diet, nutrition and supplements) Anyone looking to change their body (and mindset) should look no further.

I've worked with a few fitness coaches over the last 10 years or so and can honestly say that Giuseppe, James and the team in North London are absolutely elite-level. I have achieved the best results in the 20 years I've been training since I started working with Giuseppe. The attention to detail in the personal training sessions themselves as well as nutrition, supplementation and no BS general advice set these guys apart. Coming from a military background i thought I was training well and knew what I was doing, but there are levels to this and the BTX team is at the pinnacle of their profession. There are many snake oil salespeople in the world of fitness but these guys are the real deal, absolute experts - by using simple, effective and sustainable systems my results have been supercharged and I'm in the best shape of my life. I initially signed up for a 12-week transformation - but now that I've found BTX I'll absolutely be working with them on a permanent basis. Excited to see the results we can achieve long term. Thanks, Giuseppe and team.
