In the book introduction I stated that true HIIT workouts are cardiovascular workouts. All of the wonderful health, disease prevention, and fat loss benefits are based on these types of workouts. Plus, all of the workouts in this book are adapted from actual studies that show these fabulous outcomes. Please note that the word “high-intensity” is a buzzword in the fitness industry for any workout that is very challenging. There are countless high-intensity workouts in the fitness industry (such as boot camp and body blast), however not all of them are actual HIIT programs.

Why Is HIIT so Popular?

Recently, interest in HIIT has grown enormously due to the widespread popularity of exercise programs, including P90X, Insanity, and CrossFit, all of which include aspects of HIIT. Millions of exercise buffs have found that alternating hard-intensity intervals of exercise with light-­intensity intervals of recovery leads to enjoyable fitness gains in less time. In fact, in a 12-week 2017 study published in the Journal of Diabetes Research, it took obese sedentary women half the time to lose the same amount of body fat through HIIT training as it took them to lose it through traditional aerobic exercise. Another advantage of HIIT is the ease with which it can be modified for people of all fitness levels and health conditions. HIIT has generated a great deal of support with special populations, such as overweight individuals and those with clinical conditions like type 2 diabetes and cardiovascular disease. HIIT workouts can be performed with every kind of exercise modality, including cycling, walking, swimming, aqua training, elliptical striding, and in many group exercise classes. Also, HIIT workouts provide similar, and perhaps better, fitness benefits than continuous moderate-intensity aerobic workouts—what we call “steady-state workouts”—but in shorter periods of time.
