Abstract
A resilient golf swing practice base having a preferred swing path; an upper surface with ribbing aligned parallel to the swing path to provide a visual guide for the path; a bottom surface with ribbing aligned transverse to the path to engage the ground and inhibit movement when the base is struck along the preferred path, the bottom and top ribbing together providing the resiliency, the bottom ribbing being of graduated height to produce a convex profile to the upper surface along the preferred path. The shoulders of an aperture positioned in the base at the maximum elevation in the convex profile support the golf ball.
