Performance Physique was established by Arj Thiruchelvam in 2014, having already worked in the industry for 9 years. 

Our goal was to bring the proven scientific methods used in elite sport and nutrition to anyone who wished to make progress.

Based in Solihull, UK we offer a range of in-person and online services focussed on sports coaching, fitness and nutrition.

Over the last 19 years we’ve worked with 1000’s of clients and athletes from novices through to Olympians

You don’t have to be an elite athlete to benefit from our expertise but you can join the numerous people who have improved their health and well-being by working with Performance Physique.

Our work has contributed to the success of Premiership Football Academy players, County Cricket players, Loughborough Sports, Academy Rugby, National Rugby, National Swimming and International Water Polo.

We provide data driven results, without the jargon but in a clear and structured manner for those who truly seek to improve their performance.9
