Interval training is a training method used by athletes that compete in long-distance events. The four major aspects that govern an interval training session are the distance, speed, recovery time, and number of repetitions. Coaches favor interval training as it helps develop cardiovascular fitness and improves speed. Activities can involve running, swimming, rowing, etc. Apart from athletes, people trying to lose weight also benefit from interval training as the technique of varying the intensity of workout has been found more useful in getting people to lose weight than simply working out at a fixed intensity.
