Warming up before engaging in physical activity prepares the body for exercise by increasing blood flow to the muscles and enhancing muscle elasticity. A proper warm-up can also raise core body temperature and improve joint mobility, reducing the risk of injuries during the main workout. It helps the body transition from a state of rest to activity, both physically and mentally. Furthermore, warming up can enhance performance by priming the neuromuscular system and ensuring effective muscle engagement. These factors contribute to a more productive and safe workout experience.
