A cool-down after workouts is essential for several reasons. It helps gradually lower the heart rate and blood pressure, facilitating a safer return to resting states. This process can also reduce muscle soreness and stiffness by promoting the removal of lactic acid and enhancing blood flow to the muscles. Furthermore, incorporating static stretches during a cool-down can improve flexibility and range of motion over time. Overall, a proper cool-down can help prevent injuries and promote effective recovery, making it an important aspect of any workout routine.
