Abstract

An apparatus for sports training allows an athlete to move an exercise bar freely in two dimensions by connecting the bar between congruent pantograph trusses. The resistance offered to the movements of the user is programmable and may be varied according to predetermined parameters and also as a predetermined function of measured parameters. The apparatus further incorporates means to record the parameters of the exercise.
