Abstract: A throwing training apparatus includes at least one, but preferably two approximately parallel planar guides that are positioned behind a user relative to a throwing target. The guides have at least a portion that is planar, wherein the throwing target is in the plane of the planar portion. In one embodiment, the planar guides may be configured as tubular arcs of, e.g., approximately 180 degrees, such that the have a C shape. While a user moves his or her hand in a throwing motion, the planar guides provide tactile feedback to the user indicating when the user is breaking a desired planar throwing motion. With repetition of the throwing motion using the present invention, one may develop muscle memory of the proper throwing form, which will enable one to consistently throw with the proper form without the aid of the training apparatus.
