ok thanks. that helps. I just dont think i am good with body part awareness. when you say to only use your 'legs', what muscles should i be trying to activate. And when you say belly button, same question.
What you may be getting me to realize is more specific than what i was probably saying/thinking. However, maybe my larger question is separating the quads, glutes, hammies from 'all the rest.'. If i say that i dont feel these QGH muscles in my swing, is that a 'valid' comment?
Since IMO there isn't any 'forceful drive' from the rear leg, if you fired those muscles against an unleveraged position, they wouldn't do
So if i disregard the oblique, core, PG, conversation. Can i just ask, as people have compared this to clean and jerk weightlifting, how is the rear leg a source of power if it is not leveraged against the ground? Or are you saying there is a downward force being applied to the ground from the rear leg?
I'm not comparing the entire swing to the entire clean.
Just between the frames I had with correa and the weightlifter. In the frames of correa from 57 mph to contact and the weightlifter from bar 4-6 inches below pubic bone to full hip extension.
This is where the most force is exerted on the bat/bar in both things. By far.
As far as the right leg exerting force? Foot is behind but the leg(femur) is underneath or close to it. It can still help extend the hips. The whole point of extending the hips is to move the torso rearward/up to pull on the bat.
Check out the piazza gif very closely. He doesn't stop extending for a long time after contact and you can see it from what his feet/legs do on the follow through. His left leg gets sucked back underneath when his foot comes up and then he ends up on his right toe like michael jackson(some force there I think?).
That is perhaps the best gif of all time imo.
