Abstract: A jump training device has a substantially ladder-like element including two longitudinal bar members spaced from one another in a transverse direction, and a plurality of transverse members connected to the longitudinal members movably movable in a longitudinal direction, each of the transverse members being yieldable so that when an athlete jumping over the transverse members touches a transverse member, the transverse member yields so as to prevent injury to the athlete.
