A multi-station exercise machine has a movable subframe on which a user sits while performing various exercises. The subframe is pivotally attached to a stationery frame and is supported by a lever arm that is also pivotally attached to the stationery frame. The pivot arms coupling the subframe to the stationery frame bear against a carriage that is movable located on the lever arm. A cable and pulley system couples the lever arm to the various operable members of the apparatus so that a selectable ratio of the weight of the subframe, including the user, is communicated as exercise resistence. The amount of weight that is coupled to the operable members is selected by positioning the carriage along the lever arm. This adjustment also varies the height to which the subframe is lifted by the exercise stroke and hence the effort that must be exerted by the user.
Cette invention concerne un appareil de conditionnement physique à postes multiples qui comporte un châssis mobile sur lequel l'utilisateur s'assoit pour exécuter différents exercices. Ce châssis est monté à pivot sur un châssis fixe et supporté par un balancier également monté à pivot sur ledit châssis. Les bras pivots reliant le châssis mobile au châssis fixe prennent appui sur un chariot mobile sur le balancier. Un système de câbles et de poulies relie le balancier aux divers accessoires de l'appareil de manière à opposer à l'effort une résistance variable composée d'une combinaison réglable du poids du châssis et de l'utilisateur. Le réglage de la résistance appliquée aux différents accessoires se fait en modifiant la position du chariot mobile sur le balancier. Selon la position choisie, on fait varier la course du châssis mobile et la quantité d'effort à fournir.
