In order to exercise, we go to the gym and run outdoors. Some people have backache after running, while others have nothing to do after running. If you have backache after exercise, it proves that you haven't exercised for too long, so this will happen.

There are some other situations, let's talk about them in detail.

Too much exercise for the first time

Because some people choose to climb stairs, because the floor is too high, their body load can't bear the movement of this high floor, which will lead to muscle spasm and muscle tissue or fiber damage. Because most of the movements of climbing stairs are leg muscles, the leg muscles are sore.

Second, don't do warm-up exercises.

People who exercise regularly know which warm-up exercises are better before exercise. A certain warm-up exercise helps to activate the activities of muscles, joints and ligaments, thus avoiding some injuries during exercise. But many people who don't do warm-up exercises are prone to leg soreness.

Third, excessive fatigue

If you train when you are too tired, your body will have less function and energy. If you exercise at this time, you will not only fail to achieve the training effect, but also be prone to muscle strain and pain in the past, and leg cramps or leg weakness will occur every other day. People who usually exercise less, once the intensity of exercise is slightly higher, will be weak in muscles.

This phenomenon is normal in the early stage of exercise. The body should also have an adaptation process. As long as you keep exercising, this symptom will gradually disappear. Moreover, the body shows a better state and the walking posture is lighter. People's mental state is also full of vigor and vitality. In front of sports, everyone shows a young side without age.
