What happen if we do 100 push ups a day?

Oke so I just watch the saitama workout there is 100 push up, 100 squat, 100 situp, and 10 km run everyday, but what I really want to know is the push up. Does 100 push up can get me a good chest form? so i ran into a youtube video and I found this video.

I don’t know if this true but what do you guys think?
