A complete fitness activity includes three important parts: warm-up activity, basic activity and relaxation activity. Warm-up activities can "warm up" various organs and systems of the body, increase joint mobility, improve the elasticity of soft tissues such as muscles and ligaments, and prevent muscle injury.

After physical fitness activities, doing some moderate relaxation activities will help to eliminate fatigue, alleviate or avoid some uncomfortable symptoms of the body, and gradually restore the functions of various organs and systems of the body from the state of exercise to the state of quietness.

Extended data:

In order to prevent the occurrence of sports injuries, it is necessary to do a good job of warm-up before exercise so that the body and mind can adapt to the reaction. It must be noted that the intensity of exercise varies from person to person. Don't blindly compare with others. There is no best movement and action. Only what suits your physical condition is the best.

In addition, the elderly should pay attention to aerobic exercise when choosing sports. Aerobic exercise can promote blood circulation and has a health care effect on the heart, lungs and blood vessels. Long-term adherence to aerobic exercise can effectively increase the amount of hemoglobin in the body and improve the body's resistance.
