Answer
Dear Jay,
Try playing basketball and handball. When you play basketball you do a lot of running back and forth on the basketball court. This helps you get in shape. You have to play a lot of defense and offense on a basketball court. The foot movement, used to play defense and offense on a basketball team, are the same foot work that a football player would use during a game.

When you play handball, you do a lot of running back and forth and side to side. These are the same movements used by a the defense and offense on the football field.
Give it a try.

Your friend, Coach Louis.
