Abstract

An exercise machine includes a frame, a pivotable body support assembly, a lifting mechanism in parallel linear engagement with the frame, and a counter balance assembly connected to the body support assembly, wherein the body support assembly is pivotable from a downward position to a top position. The lifting mechanism includes a foot plate, an ankle pad, and a foot pad. The lifting mechanism also includes a lifting assist mechanism, such as a spring or gas shock. The counter balance assembly partially balances a body weight of a user as the body support assembly is pivoted from the downward position to the top position. A method of using an exercise machine includes stepping onto the foot plate and securing the back of a user'"'"'s foot against the ankle pad, releasing the lift assist mechanism, and bringing the foot plate to the toe pad.

Claims

1. An exercise machine comprising:

a frame;

a body support assembly in pivotable engagement with the frame;

a lifting mechanism engaged with the frame and adapted to lift a user into a prone position against the body support assembly; and

a counter balance assembly connected to the body support assembly and comprising a reaction arm extending from a rear portion of the body support assembly and pivotable about the frame, the reaction arm including a weight bearing end opposite the body support assembly, wherein, in operation, the body support assembly is pivotable from a downward position to a top position, and the counter balance assembly partially offsets a body weight of the user as the body support assembly is pivoted from the downward position to the top position, and wherein, when the body support assembly is in the downward position, the weight bearing end is in a raised position providing a counter balance to the user'"'"'s body weight.

2. The exercise machine of claim 1, wherein the lifting mechanism is rotatable about a lifting mechanism hinge and adapted to lift and rotate a user into a prone position against the body support assembly.

3. The exercise machine of claim 1, wherein the lifting mechanism is essentially parallel with the frame.

4. The exercise machine of claim 1, wherein the lifting mechanism comprises a foot plate with an ankle pad connected via a lifting assist mechanism to a foot pad, and wherein the lifting assist mechanism provides an upward force and brings the foot plate and foot pad together.

5. The exercise machine of claim 4, wherein the lifting assist mechanism is a gas shock.

6. The exercise machine of claim 1, further comprising a standing plate in pivotable engagement with the frame and a support member in pivotable engagement with the frame, wherein the support member pivots upward to support the weight of the standing plate.

7. The exercise machine of claim 1, wherein the weight bearing end is adapted to receive weights directly thereon.

8. The exercise machine of claim 1, wherein the counter balance assembly further comprises a cable and pulley system having a first pulley, a second pulley, a weight stack, and a cable running from the weight stack over the first pulley, under the second pulley, and to a cable arm connected to the body support assembly, wherein, when the body support assembly is in the top position, the weight stack is in a lowered position, and, wherein when the body support assembly is in the downward position, the reaction arm lifts the weight stack to a raised position providing a counter balance to the user'"'"'s body weight.

9. The exercise machine of claim 1, wherein the weight bearing end is pivotally attached to the reaction arm via an adjustment wheel, wherein the weight bearing end is angularly adjustable with respect to the reaction arm between a plurality of angular positions.

10. The exercise machine of claim 1, wherein the body support assembly comprises a chest pad assembly.

11. The exercise machine of claim 10, wherein the chest pad assembly comprises a chest pad and a chest pad frame wherein the chest pad frame is adjustable with respect to the chest pad, such that the chest pad is in slideable engagement with the chest pad frame and can be positioned at varying distances from the chest pad frame.

12. The exercise machine of claim 11, wherein the chest pad assembly further comprises at least one hamstring pad wherein the chest pad assembly is adapted to allow the user to perform hamstring exercises.

13. A method of performing an exercise, comprising the steps of:

positioning a user'"'"'s feet on a foot plate and securing the user'"'"'s ankle against an ankle pad;

rotating the foot plate, toe pad, and ankle pad about a lifting mechanism hinge of a lifting mechanism engaged with a frame to lift a user into a prone position against a body support assembly;

pivoting the body support assembly from a downward position to a top position; and

counter balancing the user'"'"'s body weight via a weight bearing end of a counter balance assembly reaction arm pivotable about the frame, the weight bearing end extending from a rear portion of and being opposite the body support assembly, such that it is in a raised position when the body support assembly is in the downward position at least partially offsetting a body weight of the user as the body support assembly is pivoted from the downward position to the top position.

14. A method of performing an exercise according to claim 13, further comprising the steps of:

orienting a user'"'"'s body prone against a body support assembly; and

moving the user'"'"'s body from a downward position to a top position by pivoting the body support assembly from a downward position to a top position about the exercise machine frame via the user'"'"'s knees.

15. The method of claim 14, further comprising, after the step of moving the user'"'"'s body from a downward position to a top position, moving the user'"'"'s body from the top position to the downward position by pivoting the body support assembly from the top position to the downward position about the exercise machine frame via the user'"'"'s knees.

16. The method of claim 14, wherein the step of counter balancing the user'"'"'s body comprises the step of offsetting the user'"'"'s body weight by adding weight resistance to a weight bearing end of a reaction arm extending away from the body support assembly.

17. The method of claim 13, further comprising the steps of releasing a lever and moving the foot plate toward the toe pad.
