The Tabata workout is a high-intensity interval training method that alternates between 20 seconds of maximum exertion exercise (such as running or body weight exercises) followed by 10 seconds of rest, repeated 8 times for a total of 4 minutes. The workout is designed to push the body to its anaerobic limits and maximize calorie and fat burn in a short period of time.
