Neighborhood Push Ups

There is this guy that lives in our neighborhood that I’ve seen a few times. He likes to do push ups. In the middle of the sidewalk, blocking the entire sidewalk. The first time I saw him he was at a bus stop, but tonight I saw him again. This time he was just down on the ground, feet should width apart, pumping out the push ups. Then he was done, popped up and walked away like nothing happened.
