Rumble Boxing Burbank #rumbleboxing Cindy Thomas & Dan Burrell detail everything about their new "Rumble Boxing" Gym in Burbank, California. @fabtv @rumbleboxingburbank At its epicenter, Rumble is a collection of the most inspired and 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 follows is an awesome orchestration of a workout engineered to 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 was a collaboration from the beginning - as if Cardi B. wrote this song, for this moment, for you, to run this shit like cardio.
