What are wind sprints?

A typical wind sprint exercise consists of jogging, sprinting very fast for a short period of time and then returning to a jog. After recovering from the first sprint, the athlete then sprints again and repeats the pattern throughout the workout.

Wind sprints are more commonly called "interval training." When doing wind sprints, a period of high-intensity exercise is alternated with a lower-intensity exercise. Interval training is used to increase fitness and to burn body fat while exercising for a shorter period of time. The name "wind sprint" was coined to indicate that the high-intensity portions of the workout consist of exercise intense enough to "wind" the athlete, or make the athlete breathe very hard.
