barrel/hand pivot point, a.k.a TTB

[BigSkyHi]

BHT is a little different then posting the bottom hand and torquing around it out front. When there is to much extension you can lose the mechanical advantage of the front shoulder and arm connection to shoulder rotation. BHT defined by Mankin isn’t losing the mechanical advantage and the front shoulder is pulling back at contact.

Is this the 'extension' you are referring to?

I think the way to build the swing is to get to positions that allow the batter to create mechanical advantage to torque the bat and reverse engineer from there.

Funny you should mention that because I’m looking at backwards chaining and reverse engineering from the follow through back.

If you don’t know where your going any path will get you there. If you know where your going the pathway is already selected.

No, I was referring to extension at contact.

No, I was referring to extension at contact.

I was hoping you were referring to torque via extension at contact, BHT?

What is this showing exactly?

How when you move the handle the barrel moves

Ok - I already knew that. I was thinking I was supposed to see supination.

Based on what i see, this is not 'supination' by definition. The barrel/forearm orientation stays locked. Supination would mean that the wrist relative to the forearm supinates. I dont believe that happens until later in the swing.
