The “step” is a 4-inch to 12-inch raised platform. You step up, around, and down from the platform in different patterns to boost your heart rate and breathing, and strengthen your muscles.
Step aerobics moves range from simple to advanced. The most basic is a step-up, step-down. Once you get more experienced, you do moves that take you over the top and around the step forwards, sideways, and backwards.
Your class will start with a warm-up, followed by choreographed routines on the step, and a cooldown at the end. In some classes, you’ll use hand weights for strength-training moves off the step.
