Abstract: Apparatuses that facilitate training for proper, repeatable throwing technique in various sports. Embodiments may provide useful feedback to a user when that user deviates from proper techniques for throwing a football, baseball, or similar item. When proper technique is used, the user may experience no interference between the training apparatus and the ball or the user's throwing hand or arm. In contrast, the user's hand, arm, or a held ball may contact portions of the training apparatus in cases where the mechanics of the user's throwing motion deviate from the proper form, thereby providing immediate feedback. In certain embodiments, the training apparatus includes a body section and attachment portions. The attachment portions may receive an upper guide structure extending from a shoulder portion of the body section and a lower guide structure extending from a hip portion of the body section.
