Rumble Flatiron/Chelsea Boxing

At Rumble, we believe the hour we spend working out can inspire the other 23 hours of our day. We believe hard work can put on some party pants and shake its hard-working ass. We believe in sharing our good vibes and energy with the world, and in many ways, it’s our most important offering. And more than anything, we believe in each other.

At its epicenter, Rumble is a collection of the most inspiring fitness instructors on the planet. Impressive athletes in their own regard, they step onto the podium at Rumble as part DJ, part motivational speaker, and complete Master of Ceremony.

The 45 minutes that follow are an awesome orchestration of a workout engineered for custom hip-hop and house mash-ups. The music, the lights, the program, and the collective heartbeat of the room all come together as if it were a collaboration from the beginning—as if Cardi B. wrote this song, for this moment, for you, to run this shit like cardio.

It’s group fitness for the individual. We believe in the power of coming together to fight for a collective goal, but we also celebrate what it means to be unique. Rumble was created to shake up the stale norms of the group fitness world, and we remain committed to less cheesy fitness B.S. and more authenticity. Let’s be real. Let’s be powerful. And let’s do it all with some style and grace.
