The main purpose of warm-up exercises before a workout is to prepare the body for physical activity, reducing the risk of injury. Warm-ups gradually increase heart rate, enhancing blood flow to muscles and improving flexibility. This process helps to raise muscle temperature, making them more pliable and less prone to strains or injuries. Additionally, warm-ups can enhance mental preparedness and focus, allowing individuals to transition effectively into their workout. A proper warm-up may include dynamic stretches and light cardiovascular activities aimed at engaging the body’s major muscle groups.
