Generally speaking, the richer the training experience, the longer the training time and the longer the muscle maintenance time. The speed of power decline is about one-third of the speed of power rise. That is to say, (relatively speaking) it grows fast and fades quickly after stopping training; After a long period of gradual training, the strength will last for a long time after stopping training. Moreover, although the strength gained by training will gradually fade after stopping training, some strength will last for a long time, even with your life. This may be why some people love sports when they are young, and their bones and muscles are better than ordinary people even if they don't exercise in middle age or old age.
According to the research, after stopping training for 4 ~ 6 weeks, after 1 month of serious training, it can be restored to the original 90%. More appropriately, the brain can remember the control process of nerves to muscles, and can save the maximum size and strength of muscles as a template. Just like building a house. It's much faster to have a blueprint than to build it blindly.
So even if you stop training for a few months, you can return to the level at that time in a relatively short time. In addition, active rest has a magical effect on the slight pain that many trainers can't get rid of, because many of this pain or joint discomfort are due to soft tissue injury, and the best treatment is rest!
