If you are not familiar with the "Tennis and Tips" subforum, the "ATP forehand" is a way to hit the forehand that is distinguished from the "WTA forehand" (among other ways) by how far back the racquet goes on the backswing. In the "ATP" forehand the racquet always stays on the hitting side of the body, while the "WTA" forehand crosses into the other side. They are named this way because the vast majority of the players in each of the tours will hit forehands that way, with a few exceptionsPlease define "ATP style Forehand."
Professional players of both genders will follow similar technique.
