Anaerobic exercise is bad for the body in that it tends to produce fatigue toxins.
The most important feature of anaerobic exercise is that it involves a very low uptake of oxygen. Due to the speed and explosive force too fierce, the body's sugar can not be decomposed by oxygen, and have to rely on "anaerobic energy".
This kind of exercise produces too much lactic acid in the body, which leads to muscle fatigue that can't be sustained, muscle soreness and shortness of breath after exercise. In fact, it is the production of a large number of pyruvate, lactate and other intermediate metabolites during fermentation, which can not be eliminated through respiration.
These acidic products accumulate in the cells and blood, it becomes "fatigue toxin", will make people feel tired and weak, muscle aches and pains, but also respiratory, heartbeat acceleration and arrhythmia, serious acidosis and increase the burden on the liver and kidneys.

Note:
1, pay attention to the intensity of the workout
Doing anaerobic exercise must choose a moderate intensity, so as to be able to achieve the effect of weight loss. That is to say, the heart rate should be maintained at more than 70% when exercising, and high-intensity exercise can consume sugar in the body and reduce the ability of muscles to oxidize fat. If you choose low-intensity exercise, the load is small. Consumption of body heat is not enough to achieve the effect of weight loss.
2, pay attention to the time of exercise
When choosing medium-intensity physical exercise, the time of exercise must be long enough to be greater than 30 minutes. Just started doing exercise does not immediately use fat to consume, because the fat from the fat reservoir inside the release, need a certain amount of time, at least 20 minutes, according to their own conditions hobbies as well as interests to choose the way to exercise, such as jogging, walking, swimming or square dancing.
