Interval training is a type of training exercise that involves a series of high-intensity workouts interspersed with rest or break periods. The high-intensity periods are typically at or close to anaerobic exercise, while the recovery periods involve activity of lower intensity.[1] Varying the intensity of effort exercises the heart muscle, providing a cardiovascular workout, improving aerobic capacity and permitting the person to exercise for longer and/or at more intense levels.[2]
Interval running provides a balanced mix of activity and rest, helping beginners gradually build their stamina and fitness without overexertion. Some interval running exercises include pyramid intervals, hill repeats, and staircase intervals.[citation needed]
Interval training can refer to the organization of any cardiovascular workout (e.g., cycling, running, rowing). It is prominent in training routines for many sports, but is particularly employed by runners.[2][3]
