“Katy is amazing! I never thought I’d be as strong or fit as I am now- after only a few months in training with her. I’ve lost over a stone and half and feel fitter and healthier than I ever have. Katy works incredibly hard and throws herself into the training sessions, which is really motivating.  She has knowledge and skill around core strength that I trust unreservedly and she’s been able to build me up to great fitness from pretty much nowhere.  Her nutrition advice has been instrumental in helping me feel fitter and stronger and she’s always on hand by email or text to answer questions or give encouragement. Katy will always go above and beyond the call of duty and I can’t recommend her highly enough! ”

Jacqui, 36 years old, London

“Katy, you transformed me for which I am eternally grateful. I never thought training could be so fulfilling, challenging and life-changing. You have set me on a new course.”

John, 64 years old, London

“Katy has been my trainer for over a year and I have found her very encouraging and enthusiastic in all aspects of her training regime. She has a lovely quiet and calm professional style and is very attuned to specific and individual problem areas, particularly for older women. Katy is constantly striving to keep up to date with all current aspects of fitness training. I have become a great deal fitter, more toned and stronger since training with Katy.  As a public health professional, I am impressed with her conscientious approach to health and fitness generally and highly recommend her.”
