[mmzqoeda] Playing catch with yourself

Throw a ball.  Run / jog / walk to where it landed, and throw it again.  Avoids the monotony of just running as exercise, and maybe gets some cross training in there with an upper body workout of throwing.  You are not pointlessly running, you are running to something interesting, namely the ball.

Baseball, with otherwise empty diamond: throw it toward the backstop, then toward the outfield.

Inspired by basketball shooting baskets: one needs to run to go get rebounds.
