Abstract

A standing single leg press exercise machine is comprised of a single movable step arranged to move up and down along an inclined path for exercising only one leg at a time. A resistance mechanism is connected to the movable step for providing resistance to movement. Two stationary steps are positioned on either side of the bottom position of the movable step. Hand rails are also positioned on either side of movable step. A shoulder pad is positioned above the movable step. A method for using the leg press is comprised of standing on one of the stationary steps with a stationary leg, and repeatedly operating the movable step up and down with an active leg. The active leg is exercised until it is tired, and the legs are switched to exercise the previously stationary leg while the previously active leg is rested.

Claims

1. A standing single leg press exercise machine, comprising:

only a single movable step arranged to move up and down for exercising only one leg at a time while the other leg is stationary, wherein said movable step has a movement range defined between a top position and a bottom position;

a resistance mechanism connected to said movable step for providing resistance; and

two stationary steps positioned on either side of said movable step adjacent said bottom position of said movable step.

2. The standing single leg press exercise machine of claim 1, wherein said movable step is arranged to move along a path slanted at about 37 degrees from vertical.

3. The standing single leg press exercise machine of claim 1, wherein said movable step arranged to slide along a slanted guide bar.

4. The standing single leg press exercise machine of claim 1, further including hand rails positioned on either side of movable step.

5. The standing single leg press exercise machine of claim 1, further including a generally horizontal shoulder pad positioned above said movable step for engaging a shoulder.

6. The standing single leg press exercise machine of claim 1, further including hand rails positioned on either side of movable step, and a shoulder pad positioned above said movable step for engaging a shoulder.
