A golf swing training aid to assist golfers with multiple skills required in the game of golf and assist the golfer in creating a repeatable impact position with all golf shots. A short portion and a parallel long portion both connect to a rear portion and define a channel. The short portion is shorter than the long portion to form a J-shaped mat. A golf ball is placed between the two portions at designated markers depending on the type of golf iron used, and the size of the divot resulting from impact can be estimated using the one or more other markers along the short and long portion to help evaluate the swing and direction of the golf club as a result of the size and direction of the divot.
