This is because muscles are suddenly subjected to long-term contraction and relaxation exercises.

Leading to the automatic synthesis of a large amount of lactic acid in the body.

Then I gained weight but it didn't hurt.

Because your exercise has been going on.

And muscles have gradually adapted to such intensity.

Decrease of automatic lactic acid synthesis in vivo

At the same time, a large amount of lactic acid is slowly decomposed in human metabolism.

So the muscles don't hurt.

Increase the training intensity appropriately.

At first, I was too eager to succeed.

Easy to cause muscle strain

Exercise should also be careful not to affect yourself ~ ~

As for whether there are long muscles.

I have to say

Consumed a part of the energy.

Part of the fat is being converted into muscle.
