**What is the importance of a post-exercise cool-down?**
The post-exercise cool-down is essential for several reasons. It helps gradually lower heart rate and breathing, preventing dizziness or fainting after intense activity. The cool-down process also aids in removing metabolic waste such as lactic acid from muscles, which can alleviate post-exercise soreness. Engaging in light activities, such as stretching or walking, promotes flexibility and reduces muscle stiffness. Overall, a proper cool-down contributes to better recovery and prepares the body for future exercise sessions.
