High-intensity interval training (HIIT) is a training protocol alternating short periods of intense or explosive anaerobic exercise with brief recovery periods until the point of exhaustion. [1] HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts.
To add challenge to the workout, each of these sprints may start at predetermined time intervals - e.g. 200 metre sprint, walk back, and sprint again, every 3 minutes. The time interval is intended to provide just enough recovery time. A runner will use this method of training mainly to add speed to their race and give them a finishing kick.
As a result, high-intensity workouts are generally kept brief. After a high-intensity workout, as with any workout, the body requires time to recover and produce the responses stimulated during the workout, so there is more emphasis on rest and recovery in the HIT philosophy than in most other weight training methods.
