Do it in a mirror and see what feelings you feel when you do it "right."
The front hip doesn't have to stay in place.
I don't know. Feelings vary.
Try feeling that you're bent over your right hip a little at the top.
Feelings are pretty unique to the person.
Just do the right thing and see what it feels like to you. Before evolvr you leaned WAY forward, so feeling a little of the proper axis tilt is going to feel "different" to you for awhile.
So I've been attempting to do some dry motions in my basement without a club and the results have been mixed.
I can definitely get the feeling of moving my right pocket towards the target and keeping my front hip pretty stationary, but my upper body really wants to cave over towards the target the moment I feel my back hip rotating.
Even when doing the wall drill, I can increase the distance between my back hip and the wall via rotation, but my torso wants to fold over forward. Its uncomfortable and I can definitely feel it in my left lat muscle when I try to really push back and try to keep the torso from folding forward. Is that a normal feeling?
I noticed @iacas in one video about hip turn you mentioned how you felt tension in your right leg and hip, I feel all of mine in my left side as a fight to keep it from collapsing forward. Is that normal or am I doing something wrong?
By bore they mean bore depth. A thru-bore trim simply adds that portion of the shaft that wouldn't be there otherwise. The important dimension is first step to heel; regardless of the bore depth. The heel is, nowadays, an imaginary point of intersection between the center-line of the shaft and the sole of the club. Working backwards from there; you can determine what, if any, modifications are necessary. A club with a bore depth of 1 and 1/8th would require less trimming than a club with a bore depth of 7/8ths...head weight being equal. The extra 1/4 inch is buried in the bottom of the hosel and does not alter the flex profile. Ralph Maltby's books are an excellent resource.
