A bat-and-ball swing training platform (STP) apparatus includes a center frame coupled to a front panel and to a rear panel to create an STP base. A rotational platform is coupled to the center frame and accessible through the front panel for rotationally supporting a user's foot. Two balance beam panels are retained in pockets defined by the center frame. A balance beam engagement slot is used to couple a balance beam to the STP base, where the two balance beam panels are coupled to create the balance beam.
