What is interval training?
According the American Council on Exercise fitness interval training is a modest to vigorous intensity effort designed to improve general fitness. Users periodically increase intensity throughout the workout. The ZTrainer uses interval training to jumpstart your metabolism and burn more calories. Its similar to your car cars burn more fuel during stop, go and slow traffic than driving at a steady speed on the highway.
Interval training is a special training technique that involves periods of maximum or near maximum exercise interspersed with periods of rest or light activity. These intervals, which can be used to enhance competitive performance in a specific sport or to improve general fitness can vary in four ways, intensity and/or duration of the “sprint” and intensity and/or duration of the “rest.” Depending on how the workout varies an athlete can train the specific energy system necessary to develop his or her sport. If you want to become a better sprinter, for instance, the Creatinine-Phosphate energy system needs to be trained. To do this, hard short sprints need to be followed by long walks. In “sprint” you go completely anaerobic then make sure you are breathing comfortably before the next sprint. During rest the ATP and Creatinine Phosphate energy systems are fully restored. The muscles say, “If I have to learn to sprint that hard, I have to make more than normal amounts of ATP between the
