High-intensity interval training (HIIT) is an enhanced form of interval training, an exercise strategy alternating short periods of intense anaerobic cardiovascular exercise with less-intense recovery periods. These short, intense workouts provide improved athletic capacity and condition, improved glucose metabolism, and improved fat burning. HIIT Me MAX! workouts include a warmup period, eight intense workout periods, and a cool down session. You can use HIIT Me MAX! with a bike, treadmill, or elliptical machine. You can play music of your choice in the background. Consult your doctor before starting any exercise plan.
