Abstract: A military press exercise machine for exercising the arms independently against a selected weight resistance includes a frame symmetric with respect to a midplane, a seat connected to the frame to define a declined exercise position for an exerciser, and a pair of levers with rearward ends pivotally connected to the frame on opposite sides of the midplane, above and behind the exercise position. Hubs located near the forward ends of the levers are adapted to hold weighted plates to resist upward movement of the forward ends of the levers with respect to the pivot connections. Handles located adjacent forward ends of the levers are adapted to be grasped by an exerciser in the exercise position and then raised upwardly in a military press motion against the weight of the plates. During upward movement, the handles move toward the midplane. When the arms are extended, the handles reside above the pivot connections of the levers.

Abstract: An improved calf exercise machine includes a frame with a seat for supporting an exerciser in an exercise position with the legs extended horizontally, a lever pivotally connected to the frame in front of and below the seat, and an engagement plate secured to the lever and adapted to be engaged and acted upon by the upper portions of the feet of the exerciser via an outward toe extension movement followed by a rearward toe retraction motion. This movement arcuately rotates the lever about its pivot axis, with a corresponding flexion and then extension of the calf muscles. Weight holding hubs connected to the lever hold a selected number of weighted plates to provide a desired weight resistance to pivotal extension of the lever via the outwardly directed foot movement. This machine optimally isolates the calf muscles during calf flexion/extension.

Abstract: A traction sled exercise machine that provides two distinct exercise cycles, each of which employs bodily force to overcome gravity and elevate a body sled and user on an inclined frame supported rail from a point of origin to a point of destination. The structure and mechanics of this apparatus permits the user to confront machine resistance in a front or rear facing anatomical position. In either instance, arm force is extended through a block and tackle leveraging system, supplemented with leg pressure on one of two sets of adjustable foot stirrups provided for leg participation in the elevation task.The body sled has a companion mechanism, called the force beam assembly, designed to help regulate machine resistance. In that assembly, the body sled is in pivotal connection with a force bar that carries a position adjustable, weighted hanger.

Abstract: A Gravity Sled Exercise Machine wherein leveraged body forces act to overcome gravity to move a two piece body sled and client upward, along biangular support rails, from a horizontal to a vertical orientation. To support the torso during the change in spatial orientation, a fixed angle sled seat reciprocates in lineal motion on the lower of two differentially inclined rails. In concurrent action, the lower section of a back rest pivots on an axle at the rear of the seat, while its upper end rides via a pivot guide on the upper, more vertically inclined rail. That kinetic linkage produces a curvilinear motion that constantly repositions the sled and introduces variable resistance to the exercise cycle.An arrangement of handrings, lines and pulleys provides the leverage for arm and upper body exercises, while Class I and II levers enable leg and lower body exercises. A flexible coupling attaches a leg lever assembly to either the static lower rail or to the moving sled seat.

Abstract: 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 resistance. 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.

The sets of weights automatically turn the three-end links on the curved supports in lifting the back cushion from a horizontal position to a vertical position as the player bends the trunk upwards, or give a pressure to the player's back as the player lies down. Either leg press can be turned into the operative position for hanging the respective leg in raising the player's center of gravity.

Abstract: A variable resistance exercise device is provided which enables a user to select from an almost limitless set of resistance curves having various shapes and amplitudes. These results are achieved using a fixed baseline resistance and a variable resistance generated by a torque arm assembly. Preferably, the torque arm assembly either has a vertical diametric torque arm and two horizontal radial torque arms which are perpendicular to the vertical torque arm or two diametric torque arms which are perpendicular to each other. By varying the position of a weight member on each of these arms, as well as the ratio of the net horizontal torque and the vertical torque generated by the weight members, the baseline resistance force that the user experiences can be infinitely varied. Additionally, through the use of a gear assembly, the user can achieve a force variance during the exercise which is greater than the minimum force experienced during the exercise.
