6 Pack Quest Secret: HIIT It To Get Lean

Done right, HIIT workouts are killers, but they don’t take a long time and they’re highly effective at burning fat and building muscle. A basic HIIT workout consists of a warm-up period, followed by several cycles of varying-intensity exercise, ending with a cool down period. The whole workout will usually take considerably less than an hour. Scientific studies show that over time, a cardio program built around HIIT can burn up to 9 times the calories as one built around long slow workouts.
