The Interval training is a type of physical training that involves training and rest periods on a periodical basis.

Interval training can be done on-court and off-court and refers to any of the cardiovascular workouts Viz., cycling, running, rowing, etc., and is one of th ewell known training routines for many sports.
Athletes in many disciplines use this type of training.
For example, you go to a athlete track and plan do an Interval training and set the time for 15 minutes.
Start your sessions first by doing your basic warm routines. A professional athletic track is 400 meters. when ready, jog/briskwalk the first 100 meters. The next 100 meters you have to increase the work intensity by running a stride. Once you cross the 100 meter mark again walk/jog for the next 100 meters. This high-low intensity, where you train the heart for low as well high intensity workout at the same time is called as the Interval training. You have to complete this training for 15 minutes. Adequate rest is essential between repetitions when you plan to again do the interval training for the next 15 minutes.
Proper cool down exercises are also to be done after the Interval training is completed for recovering from training fatigue.
