Warm up before exercising. Warm-up exercises like stretching can increase blood flow to your muscles. This makes your body ready for exercise and reduces the risk of injury. Spend 5-10 minutes warming up. Choose the right exercise. If you’re new to exercise, start with low-intensity sports like walking or yoga. Don’t try difficult exercises at first—you may hurt yourself. As you get stronger, you can gradually increase the intensity. Don’t overdo it. Exercising for too long or too hard can be harmful. Listen to your body. If you feel tired or have pain, stop and rest. It’s better to exercise for 30 minutes a day, five days a week, than to exercise for three hours once a week. Cool down after exercising. After exercise, your muscles are tight. Cool-down exercises like gentle stretching can help your muscles relax. This reduces soreness the next day. 1. Why is warming up before exercising important? 2. What kind of exercises should beginners choose? 3. How long and how often should we exercise according to the passage? 4. What should you do if you feel tired or have pain during exercise? 5.
