Warm-up exercises are essential before workouts as they prepare the body for physical activity and help reduce the risk of injuries. They increase muscle temperature, enhancing elasticity and flexibility, which supports better performance. A proper warm-up typically involves dynamics or mobility drills that stimulate blood flow to muscles and elevate the heart rate. This prepares the cardiovascular system for more intense activity. Additionally, warm-up routines help improve mental readiness by allowing individuals to focus on their upcoming workout.
