An arm exercising apparatus for developing and strengthening a person's wrist and arm muscles such as the biceps, quadriceps, deltoids, triceps, etc. The apparatus is designed to closely duplicate the sport known as arm wrestling. The exercising apparatus includes a handle that is pivotally connected to a sleeve wherein said sleeve is slideably mounted over a rod. Said connection allows a twisting action of the wrist which closely duplicates those movements and forces actually experienced in arm wrestling and further allows the handle to be automatically adjusted at the proper height for the individual user. The above described sleeve and bar assembly is further connected to a rotatable pulley shaft, wherein said pulley shaft is designed to accept predetermined weights as selected by the user, the weights being the elements which provide the resistance required by the user. The arm exerciser may be attached to a table top or platform when in use.

DETAILED DESCRIPTION The present invention is directed to an exercising apparatus of the type designed to exercise one's arm, and one which is ideal for home use and can also be used in gyms or the like.
The instant invention uses weights to provide the required tension force which the user wants to overcome.
However, the instant invention lends itself quite well to use of a fluid such as compressed air in conjunction with a pneumatic cylinder by which the desired force is applied to the pulley.
The exercising apparatus is excellent for developing upper abdominals, lower abdominals, front quadriceps, anterior deltoid, triceps, biceps, etc.
Briefly, the exerciser is a pivotally mounted handle and arm assembly connected to a weight-bearing pulley assembly.
The exerciser includes a handle which is pivotally connected to a sleeve member, wherein said sleeve member is telescopically mounted onto a rod member, wherein this rod member is pivotally connected to a second sleeve member.
Continuing, said second sleeve member being connected to a second rod member, said second rod member being telescopically inserted into a bearing member and further connected to a rotatable pulley member, said pulley member having affixed to a pulley designed for receiving weights.
The handle, as a result of the above-described connections, is automatically adjustable to any desired height without the need of physically making or changing any connections.
In use, the exercising apparatus is mounted to a stable surface and the pulley assembly is loaded with predetermined weights.
The user grasps the handle and places his elbow on the stable surface at a point which lies generally along the longitudinal axis described by said bearing member.
The user then moves the handle in a direction opposite the force generated by the weights and in a plane generally parallel to the plane described by the pulley assembly.
This arm exerciser closely duplicates arm wrestling as actually experienced by arm wrestlers.
The exercising apparatus contemplated here is simple in construction, is not mechanically complex and is economical to fabricate
