The primary goal of a cool-down after exercise is to gradually lower the heart rate and return the body to its resting state. This process helps to prevent dizziness or fainting that may occur from abrupt cessation of intense physical activity. Additionally, cooling down helps to stretch muscles, reducing soreness and stiffness while promoting recovery. Engaging in gentle movements and static stretching during the cool-down phase aids in muscle relaxation and can enhance overall flexibility, contributing to better performance in future workouts.
