Nat Miller

Nat Miller is no stranger to the Rumble Stage. It’s been over six years since she first auditioned and over four and a half years since she began her journey at the OG NYC location. A longtime NYC fitness pro now based in SoFlo, she brings nonstop energy (her caffeine addiction helps!), an electric personality, and a pure love for boxing to every class. As Head Trainer of Boynton Beach and Fort Lauderdale, Nat’s mission is simple: push herself, her team, and every client to level up — all while keeping it fun. Her classes are tough, but you’ll never be alone — she’s right there with you, pushing, laughing, and motivating from start to finish. And yes, no Nat class is complete without some hardcore rap — or Jonas Brothers — depending on the day. Truly, she’s a woman of many layers. When she’s not on stage, Nat is exploring new places and experiences around the world, living life with the same fearless intensity she brings to the studio. With a decade of fitness knowledge, an undefeated amateur boxing record, and leadership of one of the best trainer teams in the region, Nat practices what she preaches — showing that confidence, badassery, and heart go hand in hand. Step into Nat’s class and feel the energy of the authentic New York City Rumble experience.
