The purpose of cooling down after a workout is to gradually bring the body back to a resting state. This helps in lowering the heart rate and preventing blood from pooling in the limbs, which can cause dizziness or fainting. A proper cool-down routine also aids in muscle recovery by promoting blood circulation and the removal of metabolic wastes. Additionally, stretching during cool-down can enhance flexibility and reduce the risk of injury. Taking this time also allows individuals to reflect on their workout, promoting a sense of accomplishment and readiness for future exercises.
