Tabata training was developed by Izumi Tabata, Ph.D., at the National Institute of Fitness and Sports in Tokyo. It’s a timed interval method that alternates between 20-second intervals performed at maximum effort and 10-second stages of rest, repeated eight times for the ultimate exhaustive four-minute workout. It is a type of High Intensity Interval Training which is famously effective for fat loss. While TABATA training requires only one exercise, athletes are free to put together a TABATA workout from a huge array of strength and aerobic exercises. The key is simply to adhere to the 2:1 exercise-to-rest ratio, in order to incorporate a greater work load or intensity and hit a greater range of muscle groups than traditional cardio in a shorter amount of time.
