9-to-3, 10-to-2, Full Swing with HackMotion

Training different length backswings is more than just shortening a motion. By training different length swings, you'll reveal if you have a barrier to certain ranges of your swing, or if your sequence is off. If your sequence/rhythm is good, then your swing will be less susceptible to timing changes involved in different length swings.

9 to 3 is useful for training the release, impact location, and building a repeatable recovery shot from the trees.

10 to 2 is useful for training your punch shot, your wedge game, and how centered your pivot is

Full swing is useful for training your maximum power swing

I highly recommend you get in the habit of training all three in each practice.
