The New York Times presents the Scientific 7-Minute Workout, which is designed for those who are too busy to take traditional time out for exercise. The workout consists of 12 exercises performed in rapid succession using only body weight, a chair, and a wall. Based on research related to high-intensity interval training, the routine combines the fitness benefits of prolonged endurance training and weight room visits into a seven-minute session of high-intensity effort.
