2. Mastering the movement rhythm of patients with muscular atrophy requires certain time intervals. When muscles have enough rest time, fatigue can be completely eliminated, and the consumed nutrients can be fully compensated. Through excessive compensation, muscles can gradually become bigger. On the other hand, if you exercise too frequently, your muscles will not get enough rest and your muscle strength will not be enhanced. So exercise should pay attention to the rhythm, not the more the better.
3. When mastering the amount of exercise, people often choose dumbbells, sandbags, tension springs and rubber strip to increase the amount of exercise. So, what weight dumbbells, sandbags, tension springs and rubber strip should be chosen? This depends on everyone's muscle strength, which generally exceeds 1/3 of my maximum muscle strength. At the same time, pain may also be a signal of muscle injury, so we should pay attention to choose painless movements and actively treat pain during exercise.
