Warm-up exercises are essential before heavy workouts as they prepare the body for intense physical activity. They increase blood flow to the muscles, elevate heart rate, and enhance muscle elasticity, thereby reducing the risk of injury. A good warm-up also enhances the body’s range of motion and helps improve overall performance during the workout. Additionally, it mentally prepares individuals for the upcoming activity, focusing their mind and reducing the likelihood of distractions. Essentially, warm-up exercises facilitate a smoother transition from rest to intensive exertion, enhancing both safety and effectiveness.
