The importance of a cool-down after exercise cannot be overstated. Cooling down allows the body to transition from an active state back to a resting state, promoting recovery. This process helps lower heart rate and prevents blood from pooling in the lower extremities. Furthermore, a cool-down can minimize muscle stiffness and soreness by aiding in the removal of metabolic waste products like lactic acid. Stretching during the cool-down phase also enhances flexibility and maintains muscle elasticity, ultimately contributing to overall physical performance and readiness for future workouts.
