Quick Summary
High-intensity interval training, or HIIT, is a method of exercise that involves alternating short bursts of intense activity with brief recovery periods. These intense intervals typically last between 20 to 40 seconds of maximum effort, followed by 15 to 30 seconds of less intense exercise. HIIT is known for its efficiency and has been shown to be effective in decreasing body fat and increasing muscle mass. This training technique requires quick, intense bursts of exercise followed by short, active recovery periods.12
