The main goal of stretching exercises before a workout is to prepare the body for higher levels of physical activity. Stretching enhances flexibility and range of motion in the muscles, which can help reduce the risk of injuries during exercise. Additionally, it increases blood flow to the muscles and tends to improve overall physical performance. Dynamic stretches, in particular, are beneficial as they engage muscles while mimicking the movements of the upcoming workout, ensuring that the body is optimized for performance and can handle the stresses of intense activity.
