Video: High-Intensity Interval Training

High-Intensity Interval Training (HIIT) is a form of exercise done in short, intense bursts. Studies show HIIT can increase the efficiency of an exercise and have a lasting impact on metabolism after completion. Dr. Weil’s colleague, Dr. Jim Nicolai, demonstrates how to perform HIIT on a stationary bicycle.
