I can really recommend Neil Cooper from Body Active PT. He has been brilliant. Really motivating, he understands when to push me and how hard and I've been so pleased with the results. Personally, I went to him to help me lose weight and just improve my overall fitness and with his help I've made great progress, much more than I would have been able to achieve on my own!
