An arm exercising device is provided having an exercising arm adjustable to different lengths to accommodate forearms of different lengths and attached to a bearing-supported lateral rod which has an upright portion at the other end. Springs or other tension devices are attached at one end to the lateral rod and, at the other end, to a tension bar which is adjustable with respect to the base. In one variation, the tension arm can be re-positioned 180 degrees from its initial position, thereby permitting use of the device for exercising right or left arms. In a further refinement, safety stops are provided which limit the movement of the exercising arm, thereby preventing it from passing the upright position.

An arm exercising device comprising: a base; means for attaching said base to a surface; bearing means mounted upon said base; a round rod supported by said bearing means on a substantially horizontal axis, having a first end and a second end offset from said first end; a tension arm rigidly attached to said first end of said round rod and extending substantially perpendicularly with respect to said horizontal axis; tension bar means attached to said base by lateral adjustment means; first tension means connected between said tension arm and said tension bar means so that tension can be increased or decreased throughout a given range through lateral adjustment of said tension bar means with respect to said base; an exercise arm having a first end and a second end, said first end being pivotally attached by pivot means to said second end of said round rod on an axis substantially perpendicular to said horizontal axis; a first hand grip rotatably attached to said second end of said exercise arm; means for adjusting the length of said exercise arm to match forearms of different lengths; second tension means connected between said exercise arm and said round rod so that tension is created when said exercise arm is pivoted away from said second end of said round rod; a second hand grip attached to and perpendicular to said base, and spring-loaded safety stop means which, when engaged, hold said exercise arm in a position substantially perpendicular to said horizontal axis.
