A machine for training football players and wrestlers comprises a rigid U-shaped support frame (12a, 12b, 14) which supports vertical struts (22a, 22b). A crossbeam carrying a dummy (39) slides either in vertical guides (24a, 24b) or in inclined guides (26a, 26b) which have switchable cams. These cams are joined to both guides so that one of them is open when the other is closed. The upper ends of the guides have measuring device for registration of forces applied by the athlete to the dummy. By opening or closing respective guides, it is possible to use the machine for various moves, thereby developing in the athlete rapid dynamic reflexes.
