First of all, congratulations, this is a good phenomenon, because your exercise the day before achieved the effect of stimulating muscles, and your muscles produced lactic acid, which made you feel sore. I stopped going the next day. Exercise may hurt your muscles, so you can go after two days' rest. It may still hurt, but it doesn't matter. I suggest that your fitness frequency should be appropriate, preferably once every two days or once every three days. I hope my answer can help you.
