The purpose of a cool-down after workouts is to gradually bring the body back to its resting state. This process helps prevent potential injuries by reducing muscle stiffness and lowering heart rate slowly. A proper cool-down can also aid in the removal of lactic acid from the muscles, contributing to faster recovery and reduced soreness. Furthermore, taking time to stretch post-workout enhances flexibility and may improve range of motion over time. Overall, integrating a cool-down routine is essential for promoting better long-term recovery and overall workout effectiveness.
