I went to the range today and couldn’t help hitting these knockdown shots.
Basically, setup with the ball in about the middle of your stance.
Swing about half-way.
Really try to swing about 50-75% of your total effort. You need to swing easy for the knockdowns and hit it super-crisp.
Make sure your follow-through is longer than your backswing. A lot of teachers will teach you to stop at waist-level. That is not a good way since there’s a chance you might de-ccelerate. The best way is to swing nice and easy but make sure you follow-through. There is no need to abruptly stop the club. (If you watch Tiger hit knockdowns, he makes a nice follow through.)
You also want to try to see if you can get your right arm straight like the red line. (Obviously, I didn’t do that, still working on it…)
