Another Manzella Original Concept...tilt vs open

Ha ha, yes it is.

More a case of making sure I maintain access to this kind of info.

Saw this today for the first time

AmmTrainer3D™ plus AmmSensor™

Looks like a great entry into 3D

so would it follow then that on the backswing one should tilt the lower spine LEFT to allow for better hip rotation to the RIGHT?????????????

Because the spine is a curved rod and because of the discs, facet joints and other structures the spine exhibits coupled motions. Put simply, as one motion is introduced it causes another motion to occur. In the lumbar spine (low back) lateral bending is coupled with rotation to the opposite direction.

So, if you side bend the lumbar spine to the right (axis tilt) a rotation to the left (hips openning) occurs at the same time.

The coupled motion should be stated as a coupled motion within the spine. In right rotation there may be a lateral bend of the lumbar spine to the left, but the majority of rotation in the spine is allowed in the thoracic spine due to the orientation of the facet joints.

It happens based on the structure, not what a person "should do" or can do. This will not justify a lean left backswing.

Im obviously late to the party here, but I thought this was an extremely interesting thread. Thought I would post here, because had I known this earlier it would have saved some headache. No one's posted on it in two years maybe it will help some people.

Anything that can be published/shared with the public? Not asking for the results, just the approach.


Thanks,

I love a thread like this, but I gotta ask, can you really measure axis tilt and how open shoulders are with a GI Joe?
