First of all, what you need to know about fitness doesn't always change your fitness exercise, because your exercise changes so frequently that you are not even familiar with it, so the effect of exercise is naturally unfavorable to you. Some people change a set of movements every week, and your strength and muscle stimulation are not deep enough. Changing exercises is only more comprehensive, and muscle stimulation will not be better. But it can't completely change the movement. Sticking to the end of exercise makes muscle stimulation deeper, but the comprehensiveness of muscle stimulation is insufficient. So, how often do you need to change the operation? In fact, it is not based on the training time, but on the four signals that appear on the body during training. With these four signals, it means that it is time to do fitness exercises.

No muscle injury after training: If you don't feel muscle pain during exercise or the next day after training, it means that you have reached the bottleneck of muscle stimulation. If you think your training weight and intensity are ok, but you still have no muscle feeling after training the next day, then we will change our movements. Here, the function of the replacement action is to replace the stimulation site. Every movement requires different muscles. Chest muscles are also practiced, but they are also divided into upper chest, lower chest and middle seam extension. Therefore, your previous chest muscle training exercises can only stimulate the upper chest, and you should choose the lower chest when changing exercises. This will stimulate the whole chest muscle more comprehensively and cause muscle pain.

The growth of free strength is slow: many people increase muscle stimulation by gaining weight, which is a way of strength, but strength will also fall into a bottleneck. After a period of practice, the strength is not so easy to improve. For example, squat, if you often practice squat behind your neck, you will not gain two or three times your weight after practicing for a long time. In this case, you can also try to change your movements, or even reduce the training amount in order to change your movements. This can also improve the comprehensiveness of our muscle stimulation, so that the body can absorb more muscle fibers, thereby increasing muscle strength. For example, if you squat from the back of your neck to the back of your neck, you can practice squatting and hard pulling before your neck. These moves can recruit more muscles. At the same time, changing movements can also improve the coordination of the body, thus improving the exertion of absolute strength, thus breaking through the bottleneck of strength and improving muscle stimulation.

There is no burden to carry out cardiopulmonary exercise: in order to lose weight and physical training, the frequency of changing exercise is very fast. Usually I will change a set of exercises within a month or two. Because we are more familiar with an action, the corresponding body will save the consumption of the action, thus reducing the burden on the heart and lungs. Lightening the burden on the heart and lungs is not good for physical exercise and weight loss. It may reduce our weight loss and improve our physical fitness. Therefore, weight-loss athletes and physical exercise athletes usually feel that their heart and lungs are not oppressed after running or completing physical exercise, or the oppression comes too late, and they can change their behavior. For example, if you feel that running is becoming more and more familiar and the burden on your heart and lungs is not heavy, you can switch to skipping rope, so that your heart and lungs will recover.
