Fast Burn 30 uses an exercise methodology known as High Intensity Interval Training which utilizes short and intense workouts in order to burn fat. HIIT sessions can vary from 9–30 minutes and is considered to be an excellent way to maximize a workout that is limited on time.

Several scientific studies have shown that High Intensity Short Workouts can have the same if not better results than traditional aerobic type exercises (e.g. Treadmill, Jogging, Bicycling etc.) in much less time. Long aerobic type workouts have traditionally been recognized as being the best method to reduce fat. HIIT is somewhat counterintuitive in this regard, but has nonetheless been shown to burn fat more effectively. One theory suggests that HIIT may boost your Basal Metabolic Rate (BMR) which is a measure of how fast your body metabolizes food or fuel sources (like glycogen & fat into energy. Obviously the higher your BMR the faster you will lose fat (you will become and best of all, your BMR remains high even between workout sessions.
