HIIT Classes

High-Intensity Interval Training (HIIT) describes any workout that alternates between intense activity and less intense activity. Movements may be strength-based but the pace will keep it cardiovascular. HIIT workouts are becoming increasingly popular as they can produce benefits that are twice as effective as moderately intense workouts. These are generally fast-paced, short but hard classes.
