Richie,
To qualify my statement, check out "Mike Austin pivot" on Google or whatever....
Mike had a degree in kineseology (plus others) and over 90 years of golf experience when he died...
If you can find any video of him it will help...I've got 7 hours of his stuff here and video of him hitting balls at age 77 with no problem whatsoever (and long)...and he is using a 1-iron to give a lesson demonstration (how many pros would have the confidence to do that) and he hits it one handed too....
He always stated that you have to fit the golf swing to your body, not the other way around (he stated thatleads to all the "itises" you can think of,,"spondulitis, etc etc)
, and always insisted you get that right heel off the deck ASAP in the downswing to
minimise stresses...
Brgds..
