The main purpose of stretching after a workout is to promote flexibility, reduce muscle tension, and aid recovery. Stretching helps cool down the body after intense physical activity, allowing heart rate and breathing to gradually return to baseline levels. It also improves muscle elasticity, reduces the risk of injuries, and can alleviate soreness. Furthermore, post-workout stretching enhances circulation, which aids nutrient delivery to muscles and assists in the removal of metabolic waste. Implementing a regular stretching routine can lead to improved overall performance and enhanced functional movement.
