From backswing to downswing or impact

At Golf Galaxy of East Hanover I use 2 things, if it’s nice outside I will grab an alignment rod have clients set up on a downslope placing the alignment 4 inched off there lead pocket, What asking for is that they try to move toward the stick but try not to spin out. I also have a device called “the DOWN Shift” if not try with a Tennis ball cut in have an place under your Front Toes.
