The significance of stretching before and after exercise lies in its ability to enhance flexibility, prevent injuries, and promote recovery. Pre-workout stretching can prepare muscles for activity, increasing range of motion and activating the nervous system. Post-exercise stretching helps eliminate muscle stiffness and promotes relaxation. Additionally, stretching can improve circulation, aiding nutrient delivery to muscles and facilitating faster recovery. Incorporating both types of stretching into a fitness routine is vital for long-term performance and health benefits.
