Muscles don't have the pain of not practicing for a year at the beginning of each training. In most cases, there is only a little pain after training, especially after you have practiced for three years, you can hardly find that kind of pain. You can only feel a little numbness and swelling in this muscle after each training. It hurts a little to click, but the muscles are still growing and the dimensions are still increasing.

I suggest that you don't take pain as the standard of training, but should take weight as the reference.

The stupidest way is to take it for three months, and after three months, the strength will increase, that is, exercise will have an effect.
