Melissa O

A powerhouse in and out of the studio, Melissa is all about balance-pushing limits while keeping it real. She’s a Jersey girl born and raised, and a proud dog mom to Frank, her adorable tricolor Basenji (bonus points if you know the breed!). Her group fitness career started in 2015 with kickboxing, but everything changed when she took her first Rumble class in NYC. The high-energy mix of boxing and strength training was a game-changer, and by 2019, she became a Rumble trainer and learned from the best - the Rumble founders themselves. Now, she's back in NJ, bringing that OG fire to every class. By day, she's a TV producer; by night, she's in the studio, helping people unleash their strength. With her signature smile, unstoppable energy, and a knack for pushing you past your limits, Melissa will leave you stronger - mind and body - every single time.
