The arm lock putting style has the putter remaining " locked " to the golfer ' s lead forearm throughout the entire putting stroke .
The arm lock putter minimizes your ability to move your hands during the putting stroke .
With the putter against the lead forearm , it creates a bracing effect that keeps the putter head from rotating during impact and through the stroke .
A key part of the technique of using an arm lock putter is to maintain the pressure on the grip . This is done by using your trail hand to apply pressure to the butt - end of the grip to ensure the grip maintains contact with your lead forearm .
