Mark Twiggs: Head of Strength & Conditioning at Exeter Chiefs (rugby union)

Mark enrolled on the IOPN Diploma along with two other Strength and Conditioning coaches at Exeter, as well as the club’s chef after recognising the need for players to have access to world-class nutrition support. Two years on, the club’s pre-season, training and matchdays are all fuelled by the knowledge learnt on our course.

"Using the knowledge we learnt on the diploma, we changed how we fuelled our last pre-season camp and noticed a big difference in the physical performance of our players - we were able to run more intense sessions in the gym and on the pitch."
