CoreFit UK is home to some of the most decorated coaches and fighters in British combat sports. This is who you train with.
Founder & Head Coach
Henry Cleminson is one of the most accomplished combat sports coaches in the world — a coach who has guided athletes from local competition all the way to UFC World Championship glory. His coaching career spans Muay Thai and MMA, and the list of champions he has produced speaks for itself.
He is currently the striking coach for Ian Garry, who is firmly in contention for the UFC World Title, and coaches Shay Ingram as he pushes for Cage Warriors gold — continuing a track record built across two decades of elite preparation.
At CoreFit UK, the same championship-level coaching that has guided UFC title campaigns is available to athletes at every level — from absolute beginners to those chasing their first title fight.
“To be the best, you must train with the best — and at CoreFit UK, the best is exactly what you get.”— CoreFit UK · Sutton Coldfield
