Flexibility is the range of motion of a joint or a group of joints. Limited flexibility means that the range of motion of the joint is limited by the surrounding muscles and tendons. Limited flexibility will lead to posture disorder, which will lead to limited movement and eventually lead to injury. Different age, sex, specific joints, muscle mass and training background have different flexibility levels. Different customers have different degrees of flexibility, some are very poor and some are very good.

Therefore, we can make specific flexibility training methods for customers through flexibility testing.

Benefits of good flexibility:

Muscles usually overstretch when they reach the limit, overstretch, and then problems will occur. Flexibility will improve the coordination between muscle groups and strengthen the improvement of posture. Improving flexibility can relieve joint pain caused by age.

Influencing factors of flexibility:

For example, whether to exercise or not, if you exercise regularly, you may be more flexible; If the intensity of exercise is large, it will also have a corresponding impact on flexibility. At the same time, flexibility is affected by season, temperature and age. When we get old, our muscles will lose their elasticity. Flexibility is also related to gender. Generally speaking, women are more flexible than boys. For gymnasts and dancers, flexibility will be better, because training will be more targeted. Because of their own diseases, pain will inhibit the range of activities, which is the way for the body to protect itself from harm, and the corresponding flexibility may become worse!

Basic training principles of flexibility:

Relax while stretching and adjust your breathing slowly and evenly. Stretching until you feel slight discomfort, you should not feel pain, because traction receptors will be excited and limit the range of motion, providing a protective mechanism. When you keep stretching, your muscle tension will be reduced. It is best to stretch when the muscles are completely hot and the blood flow is fast. Different types of flexibility training can be combined into a set of activities. Elastic stretching should be avoided unless it is aimed at the needs of customers. It is forbidden to encourage customers to overstretch muscles and tendons to an extent that cannot be effectively controlled.

To improve flexibility, stretch 3-5 times a week, and don't exercise all at once, because it takes too much time; To maintain flexibility, stretch 1-2 times a week, and the strength should be moderate; Time, keep flexibility, 15-30 seconds, improve flexibility, 30-60 seconds.
