A golf setup training device for training a golfer to take the best possible setup in relation to a ball when addressing the ball prior to hitting the ball. The device includes a pair of axially aligned foot-positioning bars and extending therefrom at right angles a ball-positioning bar that includes a fixed section and an extendable section. The extendable section is adjustably mounted to the fixed section to adjust the length of the ball-positioning bar according to the height of the golfer and/or for a chosen iron. The device may be easily partially disassembled for compact storage.
