Fitness myth: 1, the summit will shrink, and some people will come down when they do something, such as a bird. It takes two or three seconds to get to the top. 2, the speed should be slowed down, and the muscles should have enough stimulation. 3. The number of times is less than the number of groups. Don't think that doing a lot at once will be effective. The next group can't do it. 4, to increase the displacement-that is, long displacement, some people do not move fast enough. And the movement distance of the action is too short. 5, just ask for big weight, not action standards. Very standard movements are better than heavy loads. 6, in order to quickly shape, don't let the muscles get enough rest. For example, it takes 48 to 72 hours to retrain back muscles. 7. Fishing for three days and drying the net for two days. Can't be persistent. seven
