Now it's muscle weakness, and then there will be muscle pain. All this is normal.
People like you, who have never exercised before, suggest exercising every other day to make your muscles rest and recover better.
I remember reading Schwarzenegger's autobiography before. He said he couldn't even brush his teeth the next day after he went to the gym for the first time. He picked up the cup and fell to the ground.
Also, I suggest you exercise every other day, because the key to increasing muscle volume through weight-bearing exercise is that after weight-bearing exercise, your muscles will tear slightly (don't worry), and after rest, the injured muscles will heal and be bigger than before. This is why muscles grow through weight-bearing exercise. So it can also be said that rest is more important than exercise.
Even professional bodybuilders will never practice the same muscle for two consecutive days, although they spend every day in the gym.
If you want to increase your chest muscles as soon as possible, I suggest you do four sets of push-ups. The first group is exhausted, that is, until you can't move. Remember how much you did in the first group, and then reduce each group by 3-5. Rest between each group 1 min. The movements must be standard, especially when each movement is put down, it must be controlled by muscles, and it should be put down slowly, not at once.
