Abstract: A golf putting training device includes a laterally adjustable spacing member, a pair of pivotally adjustable forearm bracing members attached on opposing ends thereof, and an adjustable strap on one of the bracing members for securing the training device to the user's forearm. The training device is adjustable to the varying spacial and angular alignments of the user's forearms and can be adjusted to accommodate a plurality of different user's forearms for use during the putting stroke. The adjustable training device correctly positions the forearms in spaced relation, and effectively stabilizes them, thus preventing relative motion with respect to one another during the putting stroke.
