I can tell if I’m hitting my forehand properly. If I’ve rotated throughout, when I catch my racket at the end of the stroke I punch myself in my nose with my right bicep. I kinda look like Reggie Jackson. He looked like a pretzel after he’d swung at a ball with a home run swing and completely missed it.

The serve, by the way, is another armless stroke. Your trunk twist and knee bend give the racket it’s momentum. Look at Michelle Wie. She rockets the ball as far as many male pros. She could hardly do that without a lot of twisting and trunk strength.

Practice Report: hit against a wall for 45 minutes, practiced my serve for a bag of balls.
