Abstract: This is an exercise apparatus and system characterized generally by the presence of a user interface member having a point of attachment to the apparatus that is positionable at different locations along an arcuate path determined, dictated and/or supported/braced by an arcuate guide. The central axis of the arcuate path may intersect the ball joint of a user. The arcuate path and the arcuate guide may lie in spaced substantially parallel planes and the user interface member be one of a rigid arm with a handle or forearm interface, or a flexible member with a free handle at its end forming the user interface. A flexible linkage forms part of the operative connection between the user interface and a weight stack or other apparatus providing adjustable resistance, with the flexible linkage being reeved through a centering pulley proximate the central axis of the arcuate member.

Abstract: This is an exercise apparatus and system characterized generally by the presence of a user interface member having a point of attachment to the apparatus that is positionable at different locations along an arcuate path determined, dictated and/or supported/braced by an arcuate guide. The arcuate path and the arcuate guide may be substantially coplanar and the user interface member be a rigid arm. The central axis of the arcuate path may intersect the ball joint of a user. The arcuate path and the arcuate guide may lie in spaced substantially parallel planes and the user interface member be one of a rigid arm with a handle or forearm interface, or a flexible member with a free handle at its end forming the user interface. A flexible linkage can advantageously form part of the operative connection between the user interface and a weight stack or other apparatus providing adjustable resistance, with the flexible linkage being reeved through a centering pulley proximate the central axis of the arcuate member.

Abstract: A multi-axes exercise machine for strengthening muscles surrounding shoulder joint of a user allows the user a range of motions about lines of motion perpendicular to an arc of circumduction of the shoulder joints. A pair of handholds is suspended from an arcuate guide plate, which extends above a user station. By moving the point of securing the handholds along the length of the arcuate guide plate, the user can re-position the upper ends of the handholds from a location above the user station to a position behind the user station. At all times, the axes of rotation of the handholds are parallel to each other and extend along a plane that contains the axis of circumduction of the user's shoulders. A centerline of each handhold passes through the center of the corresponding glenohumeral joint of the user during the exercise.

Abstract: A multiexercise weight lifting machine which features in its most basic embodiments a gearbox capable of converting the torque input through a first axle from a source of resistance (such as a weight stack) into a greater torque output at a second axle to which is connected a user interface (such as a handle); which gearbox is slidably mounted on a linear member such that the gearbox can be moved to different positions along the length of the linear member to allow different types of exercises. In its preferred embodiments it also features means for reversing the torque output at the second axle and user interface. Its numerous functions and benefits may also be supplemented by addition of a weight bench, provision of means for changing the gear ratio of the gearbox, and other features.
