It's best to exercise for a few hours.
It's definitely not good to go to the gym every day. It's best to go three to five times a week. People's bodies need to recover from fatigue, and then recover from fatigue, so that their physique can be improved. Exercise for about 2 hours at a time, and you can do less at the beginning, depending on your physical condition. If you have anything to ask, just keep asking!
