Abstract: Exercise apparatus has a weight stack for opposing a given exercise motion. The weight stack has a first set of a plurality of primary weights vertically stacked on each other, a primary weight selector having a plurality of settings selectively controlling the number of weights to be lifted during the exercise motion, a second set of a plurality of secondary weights, and a secondary weight selector having a plurality of settings selectively controlling the number of secondary weights to be lifted during the exercise motion, the secondary weights providing supplemental incremental weight.

Abstract: An inner and outer thigh exercise apparatus has a framework, and a seat and backrest mounted on the framework. Right and left leg supports are pivotally mounted on the framework about spaced apart pivot shafts relative to the seat and are interconnected with one another so as to pivot simultaneously in opposite angular directions between start and finish positions. A resistance arrangement is operatively connected to the leg supports for imposing a resistive force on the leg supports during pivoting movement thereof between start and finish positions. A motion transfer assembly is controllably mounted for selective rotation about a single pivot axis on one of the leg supports for enabling changing of the start positions of the leg supports, and allowing the imposition of resistive force on the leg supports during pivoting movement of the leg supports between start and finish positions.

Abstract: An improved abdominal bench having a simplified structure, a more comprehensive weight system, a multi-positional foot assembly and a more streamlined frame and pivoting linkages.

Abstract: An improved apparatus to enable a user to simulate skating, hereafter referred to as a skating machine, wherein the improvement involves the incorporation of a tension means connected at one end to the location of the intersection of a pedal connector bar and a crank to prevent the skating machine from locking or freezing when the pedals are at their most sideways positions. The crank is connected at its opposite end to a resistance means and the pedal connector bar is connected at its opposite end to a portion of a pedal assembly. The tension means is connected at its opposite end to a location on the skating machine frame. The crank and pedal connector bar are aligned in an almost horizontal 180 degree position when the pedals are at their extreme left or right position and the tension means prevents the machine from locking in this position.

Abstract: A bicycle training apparatus having an elevator assembly, a wheel support assembly operatively coupled to the elevator assembly, and a resistance interface assembly operationally coupled to the elevator assembly. The elevator assembly operates to raise and lower the wheel support assembly, and the resistance interface assembly provides an output signal proportional to the height of the wheel support assembly.

Abstract: An apparatus for anterior and posterior mobilization of the human talocrural joints for rehabilitation and/or therapeutic utilization. A patient's foot is secured in an apparatus and an Ankle Mortise Strap is looped around the mortise of an ankle of the foot. A force strap is attached to the ends of the Ankle Ankle Mortise Strap. Anterior mobilization is achieved by moving the force strap ventrally from the foot so that the foot including the talus remains stationary while the tibia and fibula glide anteriorly. Posterior mobilizations are achieved by securing the foot, and looping an Ankle Mortise Strap around the front of the ankle. A force strap is attached to the ends of the Ankle Mortise Strap. Posterior mobilization is achieved by moving the force strap dorsally from the foot so that the foot including the talus remains stationary while the tibia and fibula glide posteriorly.
