To improve throwing accuracy an athlete can makes use of a collapsible target training device that can be easily stored, transported, and deployed. The collapsible target training device includes multiple collapsible frames, multiple ball catching nets, a base, and a frame adjustment mechanism. The multiple collapsible frames are articulated frames that are connected in a series to form a scissors mechanism. This enables the series of collapsible frames to be extended into a tower or collapsed toward the base. The base is a rigid platform that prevents the series of collapsible frames from toppling over while extended. The series of collapsible frames is mounted onto the base so that the base is able to provide structural support and stability to the series of collapsible frames when extended to form a tower. The multiple ball-catching nets are attached to the series of collapsible frame. This positioning enables the multiple ball-catching nets to catch the balls thrown through the series of collapsible frame.
