According to one teacher, consistently ripping gloves in the heel pad is a major warning sign – not that you’re playing too much golf, but that you’re fighting a common swing flaw.
The main benefit of the Fitz Grip is that it locks the putter into your left palm, which means your left arm and putter move as one. It can also improve the alignment of your forearms.
Not only is it important to hold a golf club correctly if you want to generate power and allow it to “release” through the impact zone, it also reduces the stress placed on the joints of the arm.
