Abstract
A multipurpose exercise machine requiring only three points of adjustment centrally located. It has a one point height adjustment and two adjustments for the rotating arm assemblies. Dip and chin up bars are attached to the arm assemblies. The machine contains an integrated swingable workout bench. Through the use of a pulley system and counter balance assembly, the cable system maintains tension and provides a constant length of cable.

5. The three-point adjustment multipurpose exercise machine of claim 4, wherein said right and left arm assemblies are pivotably connected to the carriage assembly about the right and left arm axes, respectively, and having means to secure the pivotal connection and means to enable adjustment of a rotational resistance.
-
6. The three-point adjustment multipurpose exercise machine of claim 5, wherein said arms extend forward at an angle from a pivot attachment point located on the carriage and arm assembly, whereby the arms are angled to provide enough space for performing standing or seated exercises when a pure vertical resistance is required to deliver proper exercise.
