First of all, you have to find out whether it hurts or hurts. If it hurts, it means you are hurt (the more you move, the more it hurts). You should rest until it doesn't hurt. If it is sore (it doesn't hurt during exercise, it hurts when it doesn't exercise, and the acid rises), it is a normal post-exercise reaction. You don't have to rest deliberately, but you still follow the original plan.

On the one hand, you must warm up before practice; On the other hand, you must stretch and relax after practice. This helps to prevent injuries and post-exercise pain.

Usually the diet slightly increases the proportion of protein. Eat more fresh fish, eggs, milk and chicken.
