I talked a little about this new method of training the swing and snatch that Tracy and I developed during an HKC trying to troubleshoot a candidate that could not reset his hips very well after the first rep. He could do so well at the start of the hike pass but then would stay too upright for the his subsequent swings.
I fixed that by having him replace the bell on the ground for each and every rep after that, as a muscle memory drill and it worked. I just thought of it as another good cue to use with a student but Tracy took the ball and ran with it creating all kinds of new ways to program it for her classes.
The same reason touch and go benches are easier than paused benches is that the pause (somewhat) diminishes the stretch reflex and makes the lift harder. Pausing on a box before standing up requires one to overcome way more inertia and teaches one how to increase their starting strength, rate of force development as well as speed strength.
The Power swing does basically the same thing for the kettlebell swings BUT I've found I can actually use MORE weight in each set, although for significantly less reps. Getting more with less, sounds good.
