Beginners have a hard time with positioning and a harder time with shot selection. I explain where center court is. Telling someone is not enough. Showing them is still not enough. So we do imaginary rallies. They learn to serve and move back. They learn to follow shots up. At times it seems that two players have an invisible cord attached to them as one moves to center court the other gets to the ball and gets back to center while the other player moves to get the ball.
Then I have them serve and move back. I receive the serve and hit pumpkin setups to the beginner so they can learn how to move and where the ball is going to bounce. When you think about it, racquetball is a tough game to teach because everything is opposite. Usually beginners over-run almost every ball.
From this phase we move to actual drills after they have had the fun of playing. Drop and hit forehand and backhand and beginning movement consists of a drill that is not only appropriate for beginners but players of every level. I give them a setup at mid court and they have to move to the ball and stop without hitting the ball. 90% of the time athletes over-run or take the wrong trajectory to the ball.
Then I try to catch them practicing. If that happens, they are racquetball players. If not, they are probably pickleball candidates!
