Gymnasium Community


That’s why we have highly qualified, experienced and well-educated coaches. Importantly they are full time with sick-pay, pensions & holidays. There is real career progression as Gymnasium expands. They all go on regular courses across a range of fitness & nutrition specialisms and bring their knowledge back top the wider team and members.

New coaches all go through the Academy, our coach development program. We are recruiting and training coaches with a wide range of skills and backgrounds who receive a series of practical workshops, videos and our handbook to show them how we coach at Gymnasium.  They then join classes to shadow our full time Coaches before starting to lead classes themselves.

Want to join the team? Check out our Academy.
