Aerobics class with platforms

STEP

["This high-energy workout often involves choreographed moves on a raised surface to boost cardio and tone legs. Think of the equipment used, not just the activity."]

This clue points to "STEP" because it refers to a type of aerobics class where participants use raised platforms (called step benches) for cardio exercises. The word "step" directly names both the equipment and the workout style, making it a straightforward definition. No wordplay is involved—it’s a simple, literal connection between the activity and its name.
