Golf is a hard game to learn. If it wasn't, I'd be out of a job. But even though the game is hard, some people make it harder by treating the golf swing as an entirely new motion. Instead, amateurs would find the game easier if they realized that the motions they make in other spots have applications for the golf swing.

Take a player with a nasty slice. The problem is that he's keeping the clubface open through impact. However, if he plays tennis, then he already knows the motion he needs to close the clubface through impact, he's just not used to doing it with a golf club. What I do is place a tennis racquet in his hand and ask him to hit a forehand with topspin and I take a video of it. When we watch the video, he sees that he swung the racquet open-to-closed. Then I show him his golf swing, where he doesn't rotate the clubface closed. It's a very effective way to illustrate this key swing move.

Then I have my student get in his golf position with a tennis racquet and make that same topspin-forehand swing. After a few of those, he switches to a golf club. Then finally we tee up a ball. First hit: You guessed it, snap hook. For many of my students, this is the first time they've really hooked the ball. After hitting more hooks (this move takes awhile to "own"), I see students finally hitting their first true draw. It feels more powerful, too, since before they only had a glancing blow and now they are experiencing compression for the first time.
