The Strongest Physical Exorcist

In a world where demons are rampant, as a person who cannot practice exorcism techniques, all he can do is constantly improve his body. In this way, an extremely powerful physical exorcist was born. You have to ask why the protagonist is so powerful, as long as you can do 10,000 weighted push-ups, 10,000 weighted squats, and 10,000 weighted hanging leg raises every day.
