The drill could be used to discourage hitters from passing the mouse test.
I despise the drill
Lane Adams I wish you good luck! How can this instruction STILL be at the highest level? The have EVERY advantage! Every video angle...Every high speed camera...proper lighting and this is still taught?
Obviously these threads always get personal. I've looked at thousands of swings just like many of you, and this is not pushing into contact. This is arms swiveling in a vertical pinwheel motion while the lower body is turning the body horizontally through the zone.
I kicked this thread off at the request of FFS, and I didn't post the swing to start an argument. If you go back and read, you will see that I posted it to show how the actions to developing better glute engagement have helped. I did voice my opinion of it and now so have others. To that end, if anyone continues to have a desire to micro analyze this swing, please start a new thread and post it and a swing of yourself or a student doing it better.
To the topic of athletic posture and glute engagement, the body turning through the zone should be a direct result of the glutes interacting with the rear leg. The function of the core in the swing is to resist rotation and that resistance will translate into more snap at the rear leg.
I stand by the statement that I made previously in that good functioning glutes will lead to a stronger core and when glutes don't engage properly, it is common to have a weak core. Since it is easy to detect a weak core, it is easy just to point it out and have a student start doing core exercises. Unfortunately, this does not fix the underlying problem and has the painful side-effect of kicking the can 1 to 2 years down the road before someone realizes it hasn't fully fixed the issue.
So to anyone who wishes to truly help their kid or a student. Do some homework to determine if the posterior drive chain is working correctly because if it isn't and you are prescribing core workouts, you are doing a disservice to the athlete.
Jryan...best of luck to you. Obviously you work hard for your DD and that's the sign of a great father! What better compliment can I give you! The swing is the swing is the swing! More to this than the swing! She's a lucky kid! And she's obviously a willing student who works hard!
