Abstract
An improved exercise device to allow a user a natural hand position to focus the exercise on a particular muscle group or secondary task within the user's upper extremity by providing handgrips wherein a user may position their wrist in a variety of manners most functional to the individual or exercise. The device can assist users in their therapy to rehabilitate their muscles. The device and method provide a user with neutral wrist positioning while exercising by rotating the device in a circular manner about a single axis.

An arm exercise device comprising:
- a length adjustable frame having a frame axis, a first end, and a second end, wherein the first end and the second end are positioned at opposite oblique angles with respect to the frame axis;
- a length adjuster;
- a first bearing disposed within the first end;
- a second bearing disposed within the second end;
- a first tensioner, wherein the first tensioner is disposed on the first end and is structured and configured to adjust a torque of the first bearing;
- a second tensioner, wherein the second tensioner is disposed on the second end and is structured and configured to adjust a torque of the second bearing;
- a first ergonomic handgrip disposed on the first bearing, wherein the first ergonomic handgrip has a first handgrip axis that is perpendicular to a first tensioner axis;
- a second ergonomic handgrip disposed on the second bearing, wherein the second ergonomic handgrip has a second handgrip axis that is perpendicular to a second tensioner axis;
- wherein the first handgrip axis and the second handgrip axis are structured and configured to circumscribe a pair of respective planes that are parallel and do not intersect.
