When we don't exercise for a long time and suddenly do a lot of muscle training in fitness, it is likely to lead to muscle strain or muscle tension, and the degree will continue to increase, and even joint pain will occur, so we'd better do some stretching exercises after fitness, which will not only help us relieve the tension of joints and muscles, but also prevent the pain and fatigue the next day. However, if you don't stretch after fitness, the following two situations may occur.

1. Joint pain.

In daily life, we will find that when we suddenly want to exercise or lose weight, if we exercise too much, we will have leg pain or back pain the next morning. This is because we don't stretch our muscles and joints in time after exercise, which will lead to this situation. This situation shows that our body is in a state of no relaxation, and there may be some muscle or joint tension after exercise, so we must pay more attention to stretching after strenuous exercise.

2. Fatigue increases.

After strenuous exercise, we may still sweat or pant, so the next day, if we don't stretch, we may feel more tired, mainly because after regeneration, on the one hand, we consume our own calories, and at the same time, joint exercise may also lead to muscle contraction, which will lead to increased fatigue the next day. And sometimes, according to everyone's physical condition, some people may be injured or ligament strain, so you must pay attention to your own rhythm when exercising, not too fast, which may lead to your own muscle injury.

In short, if you don't stretch in time, it will probably lead to the above two situations, so you must pay more attention to stretching at ordinary times.
