What is the primary benefit of dynamic stretching before exercise?

The primary benefit of dynamic stretching before exercise is that it enhances blood flow to the muscles. This type of stretching involves movement and helps to increase circulation, which warms up the muscles and prepares them for more intense activity. By promoting blood flow, dynamic stretching raises the temperature of the muscles, making them more pliable and less prone to injury during exercise. This increased blood flow also enhances the delivery of oxygen and nutrients to the muscles, which can improve performance.

In contrast, while dynamic stretching can improve flexibility, it primarily serves to prepare the muscles for the specific movements they will perform in the workout. Additionally, dynamic stretching is not aimed at increasing muscle mass, as that process involves resistance training rather than stretching. Finally, while dynamic stretching may help to reduce post-exercise soreness indirectly by preparing the muscles for activity, its primary function is focused on blood flow and muscle readiness prior to engaging in physical effort.
