A general purpose portable pitching, throwing, or kicking device comprised of a singular one-piece supporting base with centrally located apertures for holding two spaced apart vertical parallel uprights affixed with two horizontal parallel cross members for framing a strike zone in space. The strike zone frame is fully adjustable in height, and adjustable in width from the supporting base and may be easily disassembled for transport and storage. The strike zone frame may also be adjusted to form a non-parallel shape if desired to emphasize pitching techniques. The invention is adaptable to baseball, soccer training, archery practice, lacrosse players, or the like by an appropriate choice of strike zone frame shape, size, and position.
