Led by Kristen DeMayo and Luca Smith, this high-energy workout blends cardio kickboxing, strength training, aerobics, and more — all set to an electrifying playlist spanning the 1950s to today. Move, sweat, and punch with purpose as we fight back against Parkinson’s — one song, one round, one decade at a time.

This event is open to the entire community. Registration is required to monitor capacity and ensure participant safety. Cost: $18

Proceeds benefit the Rock Steady Boxing (RSB) Fight Back Fundraiser, a national movement that brings affiliates together to raise awareness, funds, and celebrate the strength of our boxers and community.
