The Undisputed Workout™: 60 minutes of boxing, kickboxing, strength and conditioning, engineered by a 7x undefeated World Champion and calibrated to your limits. Then pushed past them.
Ratios recalibrated every session. Adaptation is the enemy. No two classes are ever the same.
Every session engineered by a world champion who trained elite pros, built to scale from first-timer to advanced athlete.
30 minutes, weekends, totally free. Come feel the Undisputed Workout for yourself. No obligation.
The Undisputed Workout™ at full intensity. Collective energy, individual output.
Direct access to pro fighters. The only system with sparring and mitt work enabled.
Full floor and equipment access. Self-directed training on your own clock.
The workout is designed for beginners to pros. Everything is on screen and your trainer walks around supporting you through every move.
Gloves and wraps are available at the front desk. Bring your bottle for free water. Dry off with complimentary towel service. Just come wearing workout gear and sneakers and you are good to go!
Group classes are you versus the bag, never another person. Sparring only exists in one-on-one personal training, if you ever want it.
No long-term commitments. No hidden variables.
Champions built this place, but everyday people fill it: teachers, engineers, parents, first-timers. Whoever you are, there's a bag and a crew waiting for you.

Output is only half the equation. Complete the cycle at the Chill Recovery Lounge: cryotherapy, infrared sauna, and recovery tech, inside UBG.
