When we pick up dumbbells to exercise, we are actually destroying our muscles, and then through rest (that is, excessive recovery), our muscles will recover to a higher level than before, so that you can feel the growth of muscles.

If you go to the gym every day, your muscles will not recover excessively, but will always be in a state of fatigue, which is very unfavorable for muscle growth.

You can arrange specific training time according to your own situation.

It takes 72 hours for a person's muscles to fully recover after training, and 98~ 122 hours for a professional bodybuilder.

1 day can take two days off or three days off. Remember not to practice the same muscle these two days or three days, that is, the muscles you practice every day are different, so that the muscles you practice can have a rest.
