RockSweat Fitness

RockSweat Fitness classes feature music from the Talking Heads, Ludacris, Drake and more, set amid club lights and big screen video -- all on a Saturday morning.

RockSweat Fitness is an hourlong, high-intensity interval training class led by Diane “Birdy” Harrison.

Diane Harrison teaches a RockSweat Fitness class as her husband DJs.

Under a disco ball and pink-purple lights, participants run and skip around the dance floor.

The workout includes one-minute spurts of high-intensity jumping or burpees.
