High-Intensity Intervals Cut Fat

High-Intensity Intervals Cut Fat
High-intensity intermittent exercise (HIIE)— repeated repetitions of a series of high-intensity exercise bouts ollowed by rest— builds fitness and decreases fat as quickly as prolonged aerobic training. An Australian study found that young overweight men practicing HIIE lost nearly five pounds and increased aerobic capacity by 15 percent. They exercised for 20 minutes, three times per week for 12 weeks. Each exercise session consisted of repeated bouts of eight-second sprints on a stationary bike followed by 12 seconds of recovery. Unfortunately, the study did not compare HIIE with traditional moderate-intensity exercise. HIIE is an effective way to lose body fat and build fitness quickly. (Journal of Obesity, (10): 480-467)
