⟩ What is cool down?
The period towards the end of a cardiovascular work out, where the level of intensity is decreased, in order to help the body adjust to normal ‘resting’ levels of exertion. For example, someone might perform a five-minute cool down period where they fast walk and gradually decrease their speed, following a 25-minute run.
Treadmills and exercise bikes tend to have a cool down option, which helps you to drop your heart rate back to normal levels gradually and safely.
