US Patent 12005306 Swing trainer balance block apparatus

A swing trainer balance block apparatus for improving balance during swing training includes a foot board having a board top side, a board bottom side, a board front side, a board back side, a board left side, and a board right side. The board top side receives a portion of a user's foot. A base support is coupled to the foot board. The base support is coupled to the board bottom side and is elastically deformable to create instability in the foot board. One swing trainer balance block apparatus is used beneath each of the user's feet to stimulate stabilizer muscles while practicing swinging a baseball bat or a golf club.
