A forward arm and a rearward arm are attached to an attachment bracket. The bracket can be attached to a putter shaft or hand grip, below the hands of a person using the device. The forward and rearward arms have upper sections that pivot relative to lower sections of the arms. Contact bars on the upper ends of the arms have contact points that touch or are very close to the forearms of a person swinging the putter properly.
