Abstract: A tackle training system defines a frame configured for attachment to a player's body. The frame has an upper portion, a lower portion, and a center portion extending therebetween. The upper portion defines at least one attachment structure extending downwardly toward the lower portion, and the lower portion defines at least one attachment structure extending upwardly toward the upper portion generally vertically aligned with the attachment structure of the upper portion. The opposing attachment structures are for contacting opposing ends of a bar so as to removably attach and extend the bar between the upper and lower portions. The attachment structures of the frame limit movement of the removable bar generally to that of the frame and allow release of the removable bar from the frame when a force that overcomes an attachment force provided by the attachment structures is applied to the removable bar.
