Related to exercise intensity are exercise time and exercise load. If the intensity is too high, it is likely to cause muscle fatigue, which will affect the attention of sports, so the risk of injury will increase. When we do exercise, we can combine aerobic exercise with anaerobic exercise, first do strength training and then do aerobic exercise, so that the exercise effect will be better. The control of exercise intensity can be determined according to the selected action group and the time of aerobic fitness. The ideal state is to have the strength to do some aerobic exercise after equipment training, so that all muscle groups can get better exercise.
