Abstract: An improved friction type exercise device of the type in which a housing has an outer wall forming a hollow cavity with a central axis. A central shaft is positioned within the cavity and positioned to allow axial and rotative movement relative to the housing when moved in one axial direction and preventing axial rotative movement relative to the housing when moved in the other axial direction. A hub is positioned in the cavity and fixed to the shaft to move axially therewith while allowing rotation of the shaft relative to the hub, the hub being nonrotatable with respect to the housing and includes a first and a second opening. A rope-like member extends through the first opening in the hub, around the shaft and out the second opening in the hub whereby when the rope-like member is pulled frictional resistance is exerted on the rope-like member in proportion to the number of turns around the shaft.

Abstract: Thus, the invention lets the user perform a whole group of buttock developing motions, working the muscle from many different angles. These motions are enhanced, through the addition of resistance. The resistance may be varied by adjusting the length of the cords and/or interchanging cords of different elastic strengths. The exercise device has cords and optionally a should and/or neck piece.

Abstract: According to the present invention, at least one adjustable resilient elastic cable interconnects a generally flat lower elongated rigid member and an upper elongated rigid member. The resilient elastic cable is attached to the lower elongated rigid member by at least one retention structure and is attached to the upper elongated rigid member by at least one connection member. Use of the back exercising apparatus in conjunction with selected exercises subjects the user's spine to vertical compression and, if desired, rotation, thereby placing traction on the spine. One or more masses may be optionally attached to the upper elongated rigid member to further increase the compression of the spine. Following termination of exercise, decompression of the user's spine yields relief of back pain.

The belt assembly further includes upper and lower back support areas extending from the belt assembly, a plurality of attachment rings connected to the belt assembly and Velcro closure strips for removably attaching the belt assembly to the torso of the user. The device further includes a pair of hand assemblies each including finger holes for receiving the fingers of the user, a hand strap for removably attaching each hand assembly to a hand of the user, and an elastic hand resistance member having attachment clips thereon for detachably connecting the hand assembly to one of the attachment rings on the belt assembly.

Abstract: An improved spring-loaded parallelogram stilt. An improved leg support attachment is provided in which the leg support is attached by a capturing bracket to the rearward vertical support. A nut and bolt pass through the capturing bracket, the bottom of the leg support and through a plastic block captured within the inside of the hollow tubular vertical leg support. A yoke structure is provided at the shoe platform level for providing further connection and adjustable support for the leg support. The yoke structure is of two pieces which surround the tubular leg support and has an inner surface made of a resilient material. The yoke structure is slidably engaged with a slot in a bracket attached to the outside of the shoe platform. The lower leg support attachment employing the capturing bracket and the yoke structure serve to prevent the leg support from accidentally becoming detached from the stilt.

Abstract: This isometric/isotonic exercise and physical therapy system is based on a series of elongated exercise rods made of urethane or other resilient, elastomeric resin that is both bendable and twistable. The exercise or therapy afforded by the system depends on the resilient exercise rod or rods; for a relatively limp, low-resistance rod the exercise is essentially isotonic, but with stiffer rods isometric exercise or therapy is provided. The system includes devices that mount the rod or rods on the person using the system for varied exercises of the knee, elbow, hip, wrist, back, or virtually any other portion of the user's anatomy.

Abstract: A fitness rope for use in both jumprope and stretching exercises is formed of a stretchable length of resiliently elastic rope. At each end of the stretchable rope length are a segment of flexible material secured at one end thereof to the stretchable rope length end, and a hollow handle of greater rigidity than the flexible segment. The handle is disposed at least in part about the flexible segment, slidable along a limited length of the flexible segment and rotatable relative to the flexible segment. Adjacent the other end of each of the flexible segments, both ends of the flexible segment are releasably joinable together to define a loop, including a respective one of the handles as a part thereof, the loop being configured and dimensioned to receive a limb or a support for use in stretching exercises.

Abstract: The present invention relates to a saucer which is adapted to be used in exercising various muscle groups. The saucer includes a frustroconical base having a lower end of a first diameter and an upper end of an enlarged diameter. A number of straps are employed on the upper surface of the frustroconical base for use in securing a user thereon. Thus, with a user secured to the upper surface of the frustroconical base, they may shift their weight in such a manner that the device no longer rests on the lower surface of the base, and thus rests upon the tapered sidewall. The user can then commence various exercising routines in an effort to exercise difficult to reach muscle groups.

Abstract: An exercise device comprising an enclosure containing water having a top surface and a bottom. A base member supported on the bottom. A seat for an exercising person is supported on the base. A float is supported in the water and adapted to be pulled through the water by a force on a cord attached to the float. The float may be air filled or filled with a lighter than water material. The float has an indicia on it to indicate the force from 1-400 pounds that the float is exerting and thereby, the force exerted on the cord by the person. A lever is attached to the handle and to the cord. The person can engage the handle attached to the cord with his hands, feet, chest or back, thereby exercising his body. The float is guided up and down by posts attached to the bottom. Multiple floats may be attached together to adjust the resistance force of the exercise device.
