Warming down after exercise is important for transitioning the body back to a resting state. A proper cool-down helps gradually decrease heart rate and blood pressure, reducing the risk of dizziness and fainting. It also promotes recovery by aiding in the removal of metabolic waste products and reducing muscle soreness through increased circulation. Stretching during cool-down can enhance flexibility and prevent injury. Overall, an effective cool-down routine is essential for maintaining physical well-being and enhancing future workout performance.
