Abstract

An exercise device that exercises both flexor and extensor muscles is provided. The exercise device includes a base having a front end, a rear end, a first side and a second side. Protruding from the rear end of the base is an anchor bar. The anchor bar may be substantially perpendicular to the base. An overhead handle bar may be pivotally connected to the top of the anchor bar by a pivot point. A stationary fulcrum may be secured to opposing sides of the base. A rotating rod is secured to the stationary fulcrum and rotates about a horizontal axis running through the rotating rod and the fulcrum. A slant board is supported by and pivots about the rotating rod.

Claims (34)

1. An exercise device comprising:

a base horizontally disposed and comprising a front end, a rear end, a first side and a second side;

a fulcrum fixed to the first side and the second side of the base;

a rotating cylinder supported by the fulcrum and rotatable relative to the fulcrum about a horizontal axis, wherein the rotating cylinder extends from the first side to the second side;

at least one slant board disposed on top of and pivotable about the rotating cylinder;

a support frame secured to the base and extending vertically therefrom;

a seat support disposed vertically relative to the base and slidably engaged within the support frame, wherein the slant board is pivotal relative to the seat support; and

a seat coupled to the seat support, wherein

the support frame guides the seat support to slide in an up and down vertical direction relative to the base when the at least one slant board pivots about the rotating cylinder.

2. The exercise device of claim 1 , further comprising an overhead handle bar attached to the exercise device.

3. The exercise device of claim 2 , further comprising an anchor bar protruding from the rear of the base, wherein the overhead handle bar is pivotally attached to the anchor bar.

4. The exercise device of claim 3 , further comprising a connecting bar comprising a top end and a bottom end, wherein the bottom end is connected to a rear portion of the slant board by a first pivot point and the top end is connected to the overhead handle bars by a second pivot point.

5. The exercise device of claim 1 , further comprising at least one handle peg attached to the seat support.

6. The exercise device of claim 1 , wherein the seat support is pivotally secured to the slant board.

7. The exercise device of claim 1 , further comprising a footpad pivotally attached to the front end of the slant board.

8. The exercise device of claim 7 , further comprising at least one foot strap attached to the footpad.

9. The exercise device of claim 1 , wherein the fulcrum is adjustable to be fixed at the front end or the rear end of the base.

10. The exercise device of claim 9 , wherein a lower portion of the fulcrum is slidably engage within a channel formed from the front end to the rear end the base.

11. The exercise device of claim 10 , wherein a plurality of notches are formed in the base along the channel.

12. The exercise device of claim 10 , further comprising a fulcrum pin bracket secured to the fulcrum, wherein the fulcrum pin bracket comprises a pin that is biased by a spring into one of the plurality of notches formed along the channel of the base.

13. The exercise device of claim 1 , wherein the seat support further comprises rollers that engage a top surface of the slant board.

14. An exercise device comprising:

a base horizontally disposed and comprising a front end, a rear end, a first side and a second side;

an anchor bar protruding from the rear of the base;

an overhead handle bar pivotally attached to the anchor bar;

a fulcrum fixed to the first side and the second side of the base, wherein the fulcrum is adjustable to be fixed at the front end or the rear end of the base;

a rotating cylinder supported by the fulcrum and rotatable about a horizontal axis, wherein the rotating cylinder extends from the first side to the second side;

at least one slant board disposed on top of and pivotable about the rotating cylinder;

a support frame secured to the base and extending vertically therefrom;

a seat support disposed vertically relative to the base and slidably engaged within the support frame, wherein the slant board is pivotal relative to the seat support; and

a seat coupled to the seat support, wherein

the support frame guides the seat support to slide in an up and down vertical direction relative to the base when the at least one slant board pivots about the rotating cylinder.

15. The exercise device of claim 14 , further comprising a connecting bar comprising a top end and a bottom end, wherein the bottom end is connected to a rear portion of the slant board by a first pivot point and the top end is connected to the overhead handle bar by a second pivot point.

16. The exercise device of claim 14 , wherein the seat support further comprises rollers that engage a top surface of the slant board.
