A pneumatic resiliency unit having a bellows with a bellows first section terminating in a bellows first section first end and a bellows first section second end, and a bellows second section terminating in a bellows second section first end and a bellows second section second end. A support surface engages the bellows first section first end and a backing plate is spaced apart from the support surface. An intermediate support platform is positioned a separation S from the backing plate and attaches to the bellows first section second end and to the bellows second section first end. The bellows second section second end is engageable with the backing plate, and spaced apart therefrom when the support surface is load free. The separation S is preferably variable to change the response of the pneumatic resiliency unit to a load applied to the support surface. Further variation in the response is provided by altering the shape of the bellows or by restricting air flow between the bellows sections. The bellows can form a closed system or an open system. Multiple pneumatic resiliency units may be combined to form an extended compliant pneumatic support surface.

The present invention is a hand and arm exercise device. The exercise device has a deformable elastic bulb having a central cavity. A first port is provided which communicates with the central cavity. A first check valve limits the flow through the first port such that a fluid can pass into but not out of the central cavity. A second port is provided which communicates with the central cavity, and with a chamber via a connecting passage therebetween. An adjustable bleed valve is provided in the passage. In one preferred embodiment the chamber is rigid, while in another preferred embodiment the chamber is elastic and a second check valve is provided in the second port to block flow into the central cavity of the deformable elastic bulb. It is further preferred that a pressure gauge be provided to the chamber so a user of the hand and arm exercise device can monitor his/her strength. The hand and arm exercise device is particularly well suited to exercises where it is beneficial to provide an isokinetic resistance against which the hand acts.

Hand and arm exercise device

A handgrip having an adjustable length having a handle terminating in a first end and a second end and a first restraining element attached to the first end of the handle and a second restraining element engaged with the second end of the handle, the second restraining element positioned a distance D from the first restraining element. Means are provided to change the distance D between the first restraining element and the second restraining element to adjust to different hand breadths and means are also provided to secure the second restraining element to the second end of the handle. A sleeve is preferably attached to the second restraining element and a detent can be provided between the second restraining element and the second end of the handle. Indicia can also be provided on the second end of the handle to indicate the setting of the adjustment means.
