In High Intensity Interval Training (or HIIT) workouts, you give maximum effort through quick intense bursts of exercise followed by short, recovery periods. HIIT workouts train and condition both your aerobic and anaerobic energy systems by getting your heart rate up and improving your cardiovascular fitness level.
In short, this means you burning more fat and calories in less time. Yes! But remember, the key words to focus on are high intensity. So keep the energy up and your rest periods short as you power through this total body HIIT.
You should be working out several times a week for at least 30 minutes before you being HIIT workouts. This workout is high impact.
