Proper exercise can keep the heart, lungs and muscles working. By enhancing the working efficiency of myocardium, excess fat and heat in the body can be removed, and exercise can improve sleep and eliminate tension. It can also keep back muscles and joints strong and flexible to prevent back pain. But don't overdo it, because exercise has many benefits. Excessive exercise, not only does not have such benefits, but will have the opposite effect.

If you feel muscle pain after exercise, it means that you exercise too much or exercise improperly. Due to excessive muscle exercise intensity or excessive exercise, the concentration of lactic acid in muscle tissue increases and accumulates. So that the nerve endings of muscles are stimulated to produce pain. Excessive exercise is not conducive to slimming. Some people exercise hard, leading to sweating and lack of oxygen, which often turns the initial aerobic exercise into anaerobic metabolism, which is not conducive to slimming.

In addition, excessive exercise can easily lead to physical and mental fatigue, fatigue of slimming exercise, and is not conducive to long-term adherence to slimming exercise.

Studies have shown that excessive exercise may lead to heart failure. Dr Schultz of university of south dakota and his colleagues published the experimental results in the journal Hypertension. In their experiments, they found that mice who often step on wheels tend to exercise excessively, and after a period of time, their hearts are abnormal. The blood pumping function is weakened. Compared with mice with less exercise, the heart failure rate of overactive mice is obviously accelerated. At the same time, experts believe that blind high-intensity training often leads to knee dislocation or ligament muscle strain.
