What is the cool-down and what is its purpose?

Explanation:

Cooling down is an easy type of exercise, done after a more heavy duty activity. This is to allow the body to gradually transition to a resting or near-resting state.The purpose of the cool-down is to bring the heartrate down to near-normal and to get the blood circulating freely back to the heart.
