When you exercise, you moderately tighten your muscles. When resting, the human body will automatically repair the damaged muscles, which is overcompensated when repairing. For example, if your skin is scratched, you will fall into a ditch. The skin has healed, not only the ditch is gone, but also higher than the original, that is, the scar. This is the truth of "excess" compensation. This is the natural function of the human body.
After a heavy training, muscle repair takes at least 48-72 hours, and the process of repair is the process of overcompensation. When you feel pain after exercise, it is actually a process of repair. If you exercise when you are in pain, it is equivalent to giving up the last chance to repair and violating the laws of nature. Therefore, I suggest you rest at least 1 day before stimulating the same muscles. If you use large equipment in the gym, you should rest for at least 2 days.
Only by scientific exercise can you grow muscles. Come on!
