A cool-down after exercising serves to gradually lower the body’s heart rate and prevent muscle stiffness. This period allows the body to transition from intense activity to a state of rest, aiding in recovery by promoting circulation and reducing the risk of dizziness or fainting. Stretching during the cool-down helps maintain flexibility and alleviate muscle tightness. Overall, incorporating a proper cool-down routine minimizes muscle soreness and enhances overall recovery, making it an essential component of a comprehensive exercise program.
