Ferris wheel or merry go round?

I’m wondering if (yet again) there’s two different definitions or assumptions being used for the same term - axis of rotation?

Maybe not so much as what it means, but _what_ is being rotated. The way FFS is using it (initial axis...), I believe he’s referring to the whole body - or at least core - being rotated.

When I read Buttermaker’s reference to the rear forearm as the axis, I interpret that it’s the bat being rotated.

What I can’t follow / figure out is if Buttermaker is saying the axis is never the lower back, and instead starts in the rear leg before switching to the rear forearm.

Also seems like there’s different definitions of separation being used - one a “+”, the other a “-“. But I can’t determine what makes one version better or worse than the other.

I know, I know... “Welcome to the technical hitting thread”.

Gags, the axis of rotation of the bat flows forward during the swing, with the initial axis of rotation being the rear lower back.

Bat doesn't go anywhere with any early zip without it being turned suddenly around the rear forearm.

Lateral side bend is another name for lateral tilt.

Most people would say they "bend" (not tilt) at the waist, just as most would say they "tilt" (not bend) their hips/pelvic girdle. Just saying...

This is a correct ... and important IMO.

As the rear elbow is becoming slotted, there is a feel/action of rotating the barrel around the rear forearm. This is accompanied and assisted with the pulling via the lead side ... there should be a marriage between the lead side pull and the arcing of the barrel around the rear forearm.

Not that it matters but the term "pelvic tilt" has been used at least since 2005. I have old "notes" from way back then with that term.
