[quote=“oldman”]Lantz,
I’m directing this question to you and hope you see this 
I understand that you don’t like the term push when describing the action of the rear leg…
If you don’t push using the back leg, how do you get the hips moving?
What’s the best way to get the center mass moving as quickly as possible?
My understanding of a faster tempo is a faster overall throwing motion is this correct?
Thanks!

Tricky, tricky…
The key is creating angles and I like the concept of getting the “butt out” for two reasons,
1: create angles that allow the CM to get in front of the shoulders,
2: Load rear hip joint
By getting the CM slightly in front, it creates positive angles. One of my favorite cues is
“Driving down on a scale, trying to weigh more while moving forward.”
I don’t like the weight to get on the ball of the foot, it’s one of the reason why pitchers often land closed. I don’t like the weight on the heel b/c it’s one of the reasons pitchers fly open with the front leg. (Everything affects everything).
By getting the “butt out”, the pitcher has positive angles with the back leg that allow them to use the ground to their advantage. I personally believe the legs have one role…
Transport the CM as quickly as possible.
Guys that push sometimes create pre-mature hip extension on the rear leg and it causes:
- stress on the groin
- Front hip dominant (swinging gate syndrome)
I also see a direct correlation with guys that push tend to crash rather than land softly and the arm action is influenced to push the ball as well.
Hope this helps.
