A golf swing training apparatus. The apparatus includes a mounting bar with an extendable length arm stabilizer extending outwardly from the mounting bar and terminating in a headrest. A swing cam is rotatable around the arm stabilizer about an axis coaxial with the arm stabilizer. A guideline extends from the swing cam and terminates in a golf club connector so that the swing cam rotates with movement of the golf club. Additionally, a pair of adjustable length guide rods extends from the mounting bar.
