1. Increases Your Metabolism
Combing high intensity with interval training results in EPOC (Excess Post Oxygen Consumption / aka After Burn), which speeds your metabolic rate and translates into a metabolism boost for up to 48 hours after a complete HIIT routine. This means you’ll still be burning fat even after you’ve left the gym.
2. Quick and Convenient
Long gone are the days of not having enough time for exercise. HIIT workouts is can be done anywhere: at home, in a hotel room, in a park, at a gym, etc. And most are 30 minutes or less! Who can’t spare that?
3. No Equipment Necessary
No dumbbells? No problem! HIIT workouts generally use only your body weight, since the focus is on getting your heart rate up and keeping it there. These workouts result in “optimal muscle building and muscle retention couples with fat loss and increased calorie burn,” says Salvador.
