Our Happy Clients

See some of the latest Google reviews left for James by the BTX Body Transformation clients.

James and the team at BTX are fantastic. They genuinely care about you as a client, and helping you achieve your goals.

Their willingness to share in their extensive knowledge, is in stark contrast to other trainers I have worked with in the past, who will keep you in the dark, wrongly believing that this will keep you coming back, as you’ll need them.

I highly recommend BTX for anyone looking to improve their health and wellbeing!

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!
