1. Warm up before fitness. Remember to avoid exercising without warming up in advance. Warm-up helps to activate muscles and make ligaments more elastic. Doing several groups of stretching exercises can achieve good results.

2. Wear a wristband and belt when exercising. Everyone has his weakness. Some people may have knee pain, while others may have wrist injuries. Elastic bandages and weight-lifting belts can provide support for connective tissue structures and prevent injuries.

3. Drink plenty of water. There is a saying among junior bodybuilders that you can't drink water during exercise. This is not correct. Replenishing enough water can avoid dehydration, which can easily lead to dizziness and physical injury.
