Abstract: Exercise apparatus and method with selectively variable stabilization enabling a user to progressively increase his/her core body muscular strength. In various embodiments, the exercise apparatus includes a resistance cabling system providing a user defined line of motion, and a partial stabilizer pad being adjustably positionable offset from the line of motion, wherein the user's core body is positionable against the pad and required to resist the torque created by the offset. The user can progressively increase the distance between the line of motion and partial stabilizer pad, in order to progressively increase the force which the user's core body must resist to maintain an upright stature. In this way, the user can progressively, over time, increase his or her core body strength.

Abstract: Exercise apparatus and method including a slidable handle assembly. In one embodiment, a support arm structure, pivotally mounted on an upright frame, enables alternatively fixed positioning of a rod at various vertical distances above a ground plane, in a generally horizontal orientation. A pair of left and right handle bracket assemblies are sildably mounted on the rod, and can be engaged by a user for moving the slidable handle bracket assembly across the rod while overcoming a resistance established by an adjustable resistance mechanism (e.g., weight stack). In one embodiment, the apparatus and method are used for developing muscles used during trunk rotation of a user in a standing position.

Abstract: A rowing exercise machine provides a declining, substantially linear path of motion while offering a consistent force angle at the grip. This allows for a fairly consistent torque application at the shoulder joint, throughout the range of motion of the exercise. The exercise machine includes an input assembly which enables a user to maintain biomechanical alignment of the user's wrist and forearm during performance of the exercise, while maintaining a consistent torque applied to the shoulder joint, in the stability of an exercise machine. The input assembly defines a declining, substantially linear path, where the user's forearms remain substantially parallel to the ground as the input assembly is drawn back.
