The purpose of a cooldown after exercising is to gradually lower the heart rate and facilitate muscle recovery. It usually involves gentle stretches and low-intensity activities to prevent dizziness and blood pooling in the extremities. Cooldown routines help prevent stiffness and soreness the following day by promoting blood flow to the muscles and aiding in the removal of metabolic waste products. A proper cooldown can also mentally transition individuals from intense exercise to a relaxed state, enhancing overall workout satisfaction.
