Abstract: A golf swing alignment system having a base rod and a centering rod that extends primarily perpendicular from the base rod, to allow a golfer to center themselves with the ball and the target. Blocks of different shapes and sizes allow the rods to connect. Additional rods are provided in some embodiments to be used for other alignment purposes, for example: a support rod and a backswing rod to assess backswing; a support rod and a follow-through rod to assess follow-through; a support rod and an inside/outside rod to assess inside-out or outside-in swing; two support rods and two hip sway rods to assess hip sway during a swing.
