    “Lewis provides a great structured work out. He’ll work with you to fine tune your sessions so go get maximum benefit. The work outs change regularly so you don’t get bored or overwork any particular areas. More than happy to recommend him for anyone wanting to improve general fitness or work on strength and muscle gain.”

    “I cannot recommend Lewis highly enough! I have faced challenges in getting back into distance running and maintaining my overall fitness. Lewis has provided me with a fresh perspective on running, allowing me to enjoy it more and ease the pressure I put on myself. The moment I mentioned my desire to run a half marathon again, he immediately encouraged me without hesitation. His enthusiasm and training plans have been exceptional. He has been a tremendous support in my daily routine, motivating me to stay accountable. Each session with him is a delightful surprise; they are always varied, and he pushes me beyond my comfort zone. Which every great personal trainer should.”

    “Lewis has eased me back into an exercise plan and I’m thrilled with the results so far - I feel stronger than I have for years! I’ve always avoided weight training in the past but I now look forward to my sessions with Lewis. He motivates me to work harder and guides me so I that am working the correct muscles, also adjusting any exercises to ensure that I don’t aggravate a neck injury from years ago. He’s also created a running plan for me which has given me the confidence to get back into running.”
