What to Expect from Open Gym Access

Open Gym is a self-paced training opportunity with access to:

  • Heavy bags, speed bags, double-end bags, and shadowboxing space
  • Strength and conditioning equipment (free weights, kettlebells, benches, etc.)
  • Our full-size boxing ring when not in use for classes or sparring
  • Mirrors, timers, mats, and everything you need to train independently

Our staff is on-site for safety and basic support, but this is non-coached time, ideal for experienced members or those following their own program.
