The present invention provides a baseball batting stance training assembly. The assembly essentially comprises a stance training mat for placement upon a baseball field or similar other playing field and at least one rearward foot-receiving cuff for removable or breakaway attachment to the stance training mat. The stance training mat essentially comprises at least three distinct zones, namely, left and right mat zones and a home plate zone. The left mat zone and the right mat zone are aligned laterally opposite the home plate zone, which home plate zone comprises a home plate marker or virtual home plate. The left and right mat zones each comprise a plurality of foot print indicia. The cuff is removably attached adjacent select rearward foot print indicia and is designed for breakaway from the stance training mat in the event of a net cuff-removing force.
