HIIT Body Pump

Pump it Up

High-intensity interval training (HIIT) involves short, intense workouts. You give a series of exercises your full effort for short bursts of 30 to 60 seconds, and follow it with an even shorter period of rest. While exercising with this type of maximum effort is difficult, it does wonders for your health.

While you're doing a HIIT workout, you're burning about the same amount of calories as you would during a typical workout like running. However, you burn more calories after a HIIT workout than you do during a steady-state cardio exercise like running, where your heart rate remains relatively stable. 

This phenomenon of burning calories after you stop exercising is called excess post-exercise oxygen consumption (EPOC). EPOC occurs when your body burns more calories healing the wear and tear from an intense workout. It's common with HIIT workouts because the exercise is so intense, and it has been linked to effective muscle growth.
