Patients can quickly build chest muscles in the following ways: 1. Patients need continuous aerobic exercise before and after chest muscle training. The main purpose of this kind of exercise is to effectively warm up before exercise and effectively discharge lactic acid deposited in chest muscles after exercise. It is recommended that patients jog for more than 20 minutes before and after exercise. 2. Patients need to find a relatively small load suitable for them to continue to exercise, that is, a small load of continuous exercise. Patients should practice push-ups first, or use equipment to exercise their chest muscles. After finding your limits, you should choose a relatively small amount of continuous exercise. For example, in the case of weak chest muscle strength in the early stage, they can do unequal push-ups, that is, the patient's feet are relatively low and the patient's hands are relatively high. Patients can put their hands on the steps and their feet under them. Through continuous low-load exercise, they can produce rapid exercise effect on chest muscles. 3. The patient needs to reach peak contraction. Peak contraction means that when the chest muscle strength reaches the maximum, it is kept for a period of time. For example, when the patient is doing push-ups, the whole body is placed in the lowest position, and then slowly pushed up after staying for a period of time. 4. Patients should ensure adequate supply of protein after exercise, such as eating protein powder.
