In many fitness places, coaches will tell students that they must warm up before training and stretch after training. Warm-up and stretching are almost accompanied by the whole exercise process, so what's the difference between them?

Warm-up, that is, when the body is still in a cool state, make it active, such as leg lifting and jogging. The focus of warm-up is to warm up muscles and improve the flexibility of all joints of the body. If the body enters high-intensity and difficult training without any preventive measures, the probability of sports injury will be greatly improved.

Arrange warm-up before training, so that everyone can confirm their physical condition and whether it is suitable for the next training. If you have abdominal pain and night sweats during warm-up, it may be that your body has issued a warning.

Stretching, that is, after all the exercises, let the muscles in the body that have been fully warmed up relax better, such as sprinting forward and backward, raising the knees and so on. Without the arrangement of strength training afterwards, the flexibility of muscles can be better extended. In addition, stretching after each exercise also helps to avoid sports injuries, strengthen training effects and shape body lines.

Arrange stretching after training, which is convenient to reduce the physical burden. Through the basic foam shaft, yoga mat and other gadgets, some basic training movements can help reduce the accumulation of lactic acid after exercise, reduce muscle stiffness and make the body no longer tired and sore.

It should be noted that stretching cannot simply replace the warm-up exercise before training. At this time, the body is still very stiff, and strong muscle stretching can only weaken the ability of the next exercise and make people more vulnerable.
