Seat assembly (40) carries an arm member support assembly (50) which includes a pair of rotary resistance assemblies (120, 130) and respective rotatively coupled arm members (64, 62) for rotation by each of the user's arms, respectively. Seat assembly (40) may be collapsed into juxtaposition over base frame (40) and partially overlaid by the foot platform (88) to releasably secure exercise system (10) in a compact storage configuration.

Abstract: An exercise device primarily for performing the so-called sit-up exercise is provided with a pivotably adjustable back-rest and a longitudinally adjustable hip-rest. The combined adjustability of the back- and hip-rests gives proper support to the back of a user during exercise and minimize the risk of back injuries notwithstanding that the spine sizes of different individuals depend on their physical particulars.

Abstract: An exerciser includes a base frame, a rotary plate, a driven rod and an elastic cord. The base frame has an upright rod, a transverse rod and two U-shaped clamping members.

Abstract: An isometric neck exerciser includes a main platform that houses three separate cushioned supports. A first of the supports is contoured and positioned to maintain firm pressure on the mid cervical spine. The second support is contoured to form a notch which is positioned to maintain firm pressure on the upper cervical vertebra and to contact a plurality of acupressure points. The third support is positioned to provide general positive support for the base of the skull. Each support reliably achieves constant support for the particular portion of the cervical system as the neck is moved through three primary axes of motion, (flexion/extension, lateral flexion and rotation). One or more stepping platforms can be added to selectively elevate the main platform to tailor the exerciser for different sized individuals.

Abstract: This exercise device extends the forearms of a human user to permit running on all fours as an animal runs. The device, usually used as a set of two, is long enough to approximately equalize the user's hip to foot distance and the distance from the user's shoulder to the device's extended end. It has a brace to be grasped by the user's hand with the back of the hand in the forward direction, with an arm embracing member to grasp the elbow end of the forearm, and a forearm support in contact with at least a portion of the wrist end of the forearm at its forward facing surface. The brace is connected to a post. The brace and post are slidable engaged and coupled by a shock absorbing coupling. The outer end of the post terminates in a foot that, during use, permits the brace and post to rotate about an axis perpendicular to the forward direction.
