According to Health and Fitness website, Greatist.com:
High-intensity interval training (HIIT) is a popular form of exercise that combines two of the most effective fat-burning methods.
The first is high-intensity training, which pushes the body to maximum effort to achieve muscle fatigue and maximum oxygen use in a quick burst. The harder muscles work, the more oxygen they require. This is measured relative to one’s VO2 max, which is the highest amount of oxygen your body consumes during exercise. Working your body close to its VO2 max triggers the afterburn effect, where the body continues to consume oxygen (and burn calories) up to 48 hours after the workout (it takes approximately five calories to consume one liter of oxygen).
The second method is interval training, which alternates periods of intense effort with periods of moderate-to-low intensity effort. Interval training boosts metabolism significantly longer than a steady workout of equal or even greater length (for example, a 20 minute workout of alternating high/low-intensity periods burns more calories than a 20 minute workout of stead intensity). Interval training also builds lean muscle tissue faster than steady state training.
By combining the above two principles, exercisers can maximize fat-burning and muscle-building potential through significantly shorter workouts. HIIT maximizes increased metabolic rate, optimizes muscle building and muscle retention during fat loss, and increases calorie burn during and after workouts.
As always, please remember these important tips:
- Remember to drink water throughout your workout to stay hydrated.
- Don’t forget to breathe while you’re doing the exercises.
- If, at anytime you feel pain beyond your usual “burn” or workout soreness – STOP immediately.
- Be careful. You should consult your doctor before starting any diet, supplements, or exercise program.
Why not maximize your weight loss efforts by adding 3 HIIT workouts just 3 times a week AND a twice daily dose of Skinny Fiber 30 minutes before meals. You’ll be thin and strong just in time for summer!
