Stretching is beneficial because it improves flexibility, increases range of motion, and enhances muscle coordination. It helps reduce muscle stiffness, lowers the risk of injury, and alleviates soreness by promoting blood flow to muscles. Regular stretching also supports better posture, relieves tension, and can ease stress. Additionally, it improves athletic performance by preparing muscles for physical activity and aids recovery after workouts, contributing to overall mobility and long-term physical health.
