The significance of warm-up exercises before a workout lies in their ability to prepare the body for physical activity. A proper warm-up increases blood flow to the muscles, enhancing flexibility and reducing the risk of injuries. It raises the heart rate gradually, allowing the body to adapt to more intense physical demands. Warm-ups also promote mental readiness, helping individuals focus and establish a workout mindset. Engaging in warming up can enhance overall performance during the workout and aid in quicker recovery post-exercise by minimizing muscle stiffness and soreness.
