1. Lose Fat and Build Muscle
Bodyweight exercises are easily done as part of an HIIT routine.
HIIT stimulates your body to produce more growth hormone and testosterone. This helps you lose body fat.
But there can be a downside to weight loss … losing muscle mass and strength.
HIIT avoids this pitfall. With HIIT you’re actively using your muscles. So they have no choice but to become stronger.
You’ll lose body fat and gain muscle tone.
