Weightlifting is a sport that requires skill and strength. For beginners, it is suggested to start from the following aspects:

1. Choose the right equipment: beginners can choose lighter barbells or dumbbells to practice.

2. Learn the correct posture: When lifting weights, you need to pay attention to your body posture, including standing posture, arm position and so on. You can refer to some teaching videos or consult a coach.

3. Gradually increase the weight: Beginners can practice from a lighter weight and then gradually increase the weight. Don't use overweight barbells or dumbbells from the beginning.

4. Pay attention to breathing: You need to pay attention to breathing when lifting weights. Generally speaking, inhale when lifting barbells or dumbbells, and exhale when lowering them.
