1, preparation before fitness is essential. You can leg press, run and move your joints as the junior high school PE teacher teaches, so that your body can be prepared for heavy exercise, especially heavy exercise, otherwise it will greatly increase the possibility of sports injury.

2. The exercise we started should focus on light load, and gradually increase the weight when we adapt. A set of standard action standards is that our body is stable and our center of gravity does not shift.

For fitness friends, diet is also very important. One of the major principles we should master is that to gain muscle, we should replenish more energy, and to lose weight, we should appropriately reduce energy supplement and increase energy consumption, so as to achieve the purpose of reducing fat.

It is necessary to replenish water during exercise. Don't drink too much water at a time. If you feel a little thirsty, drink less and drink more.

5, it is necessary to reasonably match the movements of all parts of the body, from large muscle groups to small muscle groups, from small load to large load. Hands, shoulders, chest, abdomen, buttocks and legs move together.
