Hour Blast Elmwood, Elmwood

The floor inside Hour Blast is a constantly changing exercise ecosystem. Each time students step into classes, they find a new arrangement of dumbbells, TRX bands, stability balls, and other high-intensity training gear meant to work every muscle in the body. Yet those items make up only part of Hour Blast's signature 60-minute workouts. That's because the instructors combine floor time with interval treadmill work during each class to keep heart rates elevated. Yet workouts are scaled based on ability: whether participants do their intervals at a walking, jogging, or running pace depends on their skill level or the number of wheels embedded into their shoes.
