Meat dissolves in the blood. 2. hormonal imbalance. Hormone disorder will make our body feel tired, and it will also make our body cramp, making it difficult for our body to return to its original strength level. 3. Heart damage. Because in the process of training, our body will continue to be excited and release a lot of adrenal hormones, which will make our heart beat violently and cause insufficient blood supply. If it lasts for a long time, then I will feel pain in our hearts, and in more serious cases, it will lead to sudden death, so we must not be careless when training. 4.

In our old age, if the joints are badly worn, it will have a great impact on our lives. When we do a lot of training, dehydration and anemia will affect our health. You will sweat a lot. If we don't replenish water in time, our body will lose a lot of water. These hazards I mentioned above are all caused by excessive exercise.
