A golf swing training aid comprises a set of components which include a substantially cylindrical grip bar with a first larger end tapering to a second smaller end so as to resemble the grip portion of a golf club. The grip bar has a first attachment eye at its first end. An extendable tensile member with first and second attachment affordances at its ends, such as clips or formed wire hooks, is attached to the first attachment eye at one end and a second attachment eye at the other end. A foot band attachment bracket has a second attachment eye and a base plane which is stepped upon for stability while a user exercises or practices golf swings while working against tensile resistance developed in the tensile member. The attachment component may be formed of sheet metal or made of formed metal wire in whole or in part.
