“A GREAT EXPERIENCE - HIGHLY RECOMMENDED I got in contact with Jimmy because of some stubborn weight I was carrying after going through IVF. He immediately put me at ease when I was discussing my challenges with him and started making a plan and outlining what I could look into and what he can help me with. Jimmy is great to talk to and a nice person but is also very knowledgeable in the field of nutrition. I considered myself pretty informed in the subject but still learnt a massive amount of new information during our sessions. I'm still applying the knowledge I gained every day, drinking enough water being my easy win. If you're looking for somebody who's an expert but will also flex to the way that you want to approach your nutrition, Jimmy is the person for you.”

“Jimmy was firstly, a really good person and really listened to the issues I had after injury. He understood my goals and how I wanted to start playing football again. Sessions were just the right level of hard work but still fun and motivating to get better and improve. I'd recommend Jimmy to anyone looking to train and improve for a sport they love.,.he was brilliant!”

“I strongly recommend Jimmy for his professionalism.
He has been able to identify the methodology to help my player who today is a serious tennis player who can think of embracing a professional tennis career.”

“ We have worked with Jimmy for two years and found him both knowledgeable and professional. Communication was very good and a program that changed according to needs and physical development was developed and updated on a monthly basis which we found most helpful”
O.F - Walton on Thames - Surrey
“I really enjoyed our sessions together, the confidence that I have gained has amazed me and the way I feel in terms of strength and physical shape is also better than I had imagined. My understanding of my food intake and how that relates to my exercise levels means I can enjoy more food with confidence again and feel I am eating the right things at the right time to build my weight back up in a healthy way.”

“Great experience - I recommend!
Back in May 2016 I contacted Jimmy to help me with a marathon training plan and a nutrition assessment. He helped me to clarify my goals and put in place a clear training schedule and a sport diet. I learnt pre and post stretching exercises and what food can help to support my training plan.
I recommend "Vivere Fortis".... I ran Dublin's marathon in 3:37' (my Personal Best). ”

“I approached Jimmy last year to help me with my weight loss challenge. We had about a dozen sessions where Jimmy helped me with my exercise regime, focussing on technique. With motivation from Jimmy I managed to do more than I had done before and successfully lost about 1 stone in weight.”
