Swing experiment

[Bonesaw]

I think TM's focus on getting the back leg internally rotating fast/early/on time(whatever way you want to look at it) helps alot of lower level players get better hip extension in their swings. Not sold on hand path. Or that its truly "one legged". But the back leg needs to external rotate on load then internal rotate into extension. Hip cant extend as easily when the femur is not close to being in line with the torso.

Watch freeman, lindor and springer especially. And both judge and bonds. Really fast hip extension right before/during contact because back knee is pretty close to front knee.

Not sure you can teach someone to extend hips like this as much as you can get them in a great position to do so.

Edit: Shawn you look pretty good with extension I think. At least compared to me.

Sorry for a double post but Springer, freeman and lindor were in the other thread. Here they are.








That kind of hip extension looks pretty similar to the way this lady is able to throw 250+ lbs right over her head. Maybe its her obliques though.

I think the psoas plays a big role in hip extension in the swing.

Ok. Is that sarcasm?

LOL, No sarcasm. There is a guy Hubie (Mike Huber) who bases everything on the psoas muscle. He says you arch the lower back from a leverage position off the back heel to initiate the swing. This brings the hips into the swing, hip extension playing the dominant role. The psoas creating the hip extension or responsible for hip action in the swing.

Haha you can never be too sure around here.

I say that because psoas is the most powerful hip flexor. It is very imoportant I think because it loads the hip extensors(think glute and back of leg).

Hip extension is when the body straightens out. Torso pelvis and femur all in a line.

Check out your swings and the swings of all these pros. The tilt toward the catcher allows them to straighten that much more. Maybe a few inches more.

Then watch the lady weightlifter. She waits til the bar is about 6 inches from her pubic bone to extend. If she early or late extends or loses posture she loses a lot of power.

Actually the psoas does create hip flexion. You are correct. I should have said that using the psoas through arching the lower back brings the hip extenders into play.

While I don't think that the swing is truly one legged with the front leg being landing gear, the TM movement most closely matches how Bonds externally rotates his back leg to open his pelvis and set it up for the hip and knee extension of the front leg. The pelvis being turned to receive the rearward push of the front leg creates a perpendicular leverage position to torque the pelvis.
TM's drill movement is part of what Bonds actually does and isn't a feel vs real situation.
I think that TM's focus on torquing the barrel and ferris wheel swing plane results in early bat speed and more importantly getting on plane early.
While some say all swings TTB, when do they TTB? Bonds does it early and so it makes sense that he is swinging down because he gets the barrel moving downward early, down in the back.
Early TTB demands orienting the arms so the barrel can rotate around the rear forearm axis. Tilt aligns the bat plane to the pitch.
Here's pics of Bonds and Judge at foot plant.
Bond's pelvis is opened more than AJ's. Bonds does it better.
Bonds has a more upright stance, actually tilted back, chest up, so he pushes more against his front heel and is more in his glutes than Judge who is more in his quads....posterior vs. anterior chain.
The internal rotation of the back leg after it leaves the ground it's just a recoil and reposition to catch the hitter as he completes the swing.

Yeah I think thats pretty accurate. They cant really extend if theyre not flexed in the first place.

Bobby,

Is the rear hip not extending also? Couldnt that drag the rear foot into the air sometimes on some hitters?
