A new Rotary Exercise Machine for offering a more efficient and effective machine for exercising the deltoids, the pectorals, the external obliques, and the abdominus rectus, the quadriceps, and the calves of a human body. The inventive device includes a top plate, a bottom plate, a resistance plate, and a resistance knob. In use, after the Rotary Exercise Machine 10 is assembled and operable, the user stands upon the exposed surface of the top plate 20 and begins a twisting exercise motion. Upon a first try, the user then adjusts the tension of the Rotary Exercise Machine 10 by operation of the resistance knob 40. After adjusting the tension of the Rotary Exercise Machine 10, the user begins to exercise.

A Rotary Exercise Machine comprising: a top plate, a bottom plate, a resistance plate, and a resistance knob; said top plate being rotatably mounted on said bottom plate, said resistance plate being fixedly mounted on said bottom plate between said top and bottom plates such that said top plate is rotatable with respect to said resistance plate; said top plate having an aperture therethrough at a location radially spaced from the center of rotation between said top and bottom plates, said resistance knob including a threaded resistance knob shaft threadedly mounted in said aperture in said top plate, said top plate having a top plate rim extending in a substantially downward direction from the outer perimeter of said top plate and a brake reaction wall mounted to said top plate rim and extending inwardly in a direction substantially parallel to said top plate; wherein a portion of said resistance plate is located between said brake reaction wall and the lower end of said resistance knob shaft such that selective rotation of said resistance knob advances said resistance knob shaft toward said brake reaction wall to produce a pinching of said resistance plate between said resistance knob shaft and said brake reaction wall to apply a variable amount of braking force between the resistance plate and the top plate and thereby vary the resistance exhibited by said top plate to rotate with respect to said bottom plate.
