Warm-up prior to exercise means doing light physical activities before starting your main workout. It helps prepare your muscles, heart, and lungs for more intense movements. Warm-ups also reduce the risk of injury and help improve performance by increasing blood flow and flexibility. Doing warm-ups for about 5–10 minutes can make a big difference before any physical activity like sports or workouts.Examples of warm-up exercises:Light jogging or walkingArm circlesHip swingsLeg swingsShoulder rolls
