Abstract: A punching bag useful in training fighters in developing an effective uppercut includes a vertical member for attachment to the wall having disposed rotatably thereon a horizontal bar containing on its end a padded arm terminating in a rounded portion which simulates the chin of a fighter. The horizontal arm is limited in its downward travel by a hard rubber stop and is biased to the horizontal position by a heavy tension spring but is free to rotate upward against the tension of the spring allowing the training fighter to practice uppercuts on the end thereof and develop the necessary muscles required for such a punch.
