This gym’s “no entry after 5 minutes” policy is completely unreasonable. Everyone in NYC knows how unreliable the subway system can be, especially on weekends yet Rumble shows zero understanding or compassion for people who make the effort to show up.
I arrived just a few minutes late, was denied entry, and on top of that, got charged a $40 no-show fee. So basically, they took $80 from someone who actually showed up. How is that fair? It feels cold-hearted, greedy, and totally inconsiderate of people’s time and effort.
Really disappointing experience. Never again. Avoid this location and spend your money somewhere that values its customers.

Rumble Strong Comes in STRONG!
Even though Rumble UES is closed, the Chelsea and NoHo studios are bringing fresh energy.
The new Rumble Strong class is a game changer! 45 minutes of nonstop dumbbell training that works every muscle. You’ll push, pull, and lift in ways that wake up muscles you didn’t even know you had.
I took the very first Strong class with Bradford at Chelsea and he crushed it. Clear, motivating, and always fun to train with. He teaches it at both Chelsea and Noho. Be ready to get up and catch the sunrise to be a part of this. You won’t regret getting a “STRONG” start to your day.
This class isn’t just a killer strength session it levels up your technique on the bag too.
