Four HYROX classes a week
Teesside's official HYROX affiliate gym
HYROX is the fitness race that mixes running with functional stations like sleds, SkiErgs, rowers, wall balls and sandbags. Mas Body Gym was the first gym in Teesside to become an official HYROX affiliate, so the kit (official sleds, wall balls, sandbags and kettlebells, Concept2 rowers and SkiErgs), the formats and the coaching are the real thing. Mike Hind MBE is a Level 1 HYROX coach and Ashleigh is a qualified HYROX instructor. You do not need to be racing to train with us: the classes scale to every level.
Included with every membership
Recovery room: ice bath, sauna, compression and massage
Most gyms sell you the work. We also sort the recovery. Every membership includes the recovery room, with an ice bath, an infrared sauna, a massage chair, Pulsio Air compression boots with leg and hip attachments, and massage guns. No booking, just walk in after your session. Not a member yet? A gym and recovery room day pass is £15.
