The operator exercises by gripping a palm bar in each hand. Each end of a static or non-stretchable line or cord is run through a tunnel within a respective palm bar and secured therein, usually with a knot. A pivoting impinger is installed within the palm bar so that its head swings into the bottom of the tunnel against the static line to keep it from slipping out of place. Each end of a different cord, a stretchable one, is anchored within the ends of the palm bar with its mid-portion, usually...

The grip strength device is configured to gauge the grip strength of contracted muscles or aid in exercising particular muscles by providing resistance against the contracted muscles. The grip strength device is inserted into a user's vagina or held in a user's hand. The user either contracts the pubococcygeal or hand muscles depending on the casing used. The grip strength device has a removable casing containing a first fluid, a first bellows, a second bellows and a pressure gauge. The first be...

A resilient ball is supported in place on a chair, exercising equipment or other support by a strap or metal clip for periodic exercising of hand and arm muscles. The strap may be one piece or segmented and provided with fabric closure pieces. The ball is secured to the strap or clip by a threaded fastener or a tensionable cord. Non-metallic elements isolate the threaded fasteners from damaging contact with supporting structures.

An exercise device includes a housing having at least a wall portion, at least two apertures extending through the wall portion and spaced from each other, and at least one elongate rod having a center section located between opposite ends. The center section is adapted for slidable movement through the apertures. The friction generating arrangement provides frictional engagement of the elongate rod with the apertures, so as to resist sliding movement of the rod through the apertures.

The invention is a semi-resilient exercise grip that has a non-resilient particulate core surrounded by a resilient rubber covering. Within the core there is also a dry lubricant such as talc that allows the particles to move over each other without damage. The outer covering may consist of a single thick latex layer, a thin latex layer surrounded by a thick rubber layer or a number of thin latex layers. The semi-resiliency of the grip enables a user to deform the grip and thereby change its sha...

An exercising device made out of a single moulded piece of plastic for exercising the grip, wrist, the forearm of a golfer. One end of the device is a soft, squeezable knob. The other end is a tubular chamber moulded onto one surface of the knob and provided with a plastic rod positioned in the chamber and extending from the knob end of the chamber out beyond the opposite end of the chamber. The portion of the rod outside the chamber has a hole therethrough. By sliding the chamber over a hollow ...

The present invention concerns that of a new and improved apparatus for exercising, conditioning, and strengthening various hand, wrist, and forearm muscles. The apparatus comprises a central coil that has two attached handles. By squeezing the handles, an individual can strengthen various hand, wrist, and forearm muscles. An adjustment mechanism is enclosed which will allow an individual to change the tensile strength within the central coil, requiring a greater amount of power to move the hand...

A method and apparatus are provided for exercising a hand. A doughnut-shaped elastomer is provided. The elastomer is held with the bottom portion nested in the bottom of the palm of the hand and with the top portion gripped by the four fingers of the hand. As the fingers squeeze the elastomer, the top portion of the elastomer rolls or twists while the bottom portion of the elastomer remains stationary in the palm of the hand. The twisting of the top portion causes the elastomer to bow or arch in...

An improved structure finger strengthening device, the design of which features elastic components installed between upper and lower housings and finger sleeves. The fingers of the user are inserted into the finger sleeves, the fingers then forced outward and relaxed inward for conditioning and drilling. At the same time, the present invention provides for simple assembly and component replacement.
