دانلود کتاب High Intensity Interval Training

HIIT, or High-Intensity Interval Training, is a new workout trend that involves short, intense bursts of exercise following by periods of lower-intensity exercise or rest. The science behind HIIT is that through these intense bursts of activity, the body burns more calories in a shorter period of time than traditional exercise routines that take longer and provide less fat-burning benefits. Although HIIT may just sound like another trend, there's considerable science that says the benefits are real, and it's considered to be one of the most efficient and effective ways to get in top physical condition and burn more fat in less time. Idiot's Guides: High Intensity Interval Training is a full color, visual guide that is packed with over 80 exercises, structured routines, and fun yet intense programs that can be done anywhere, and at any time. Step-by-step, readers will learn how to do exercises the right way and reach a new level of fitness and reap fitness benefits that other, more traditional workouts can't offer.
