## Abstract

Various device and method embodiments for an exercise device are provided. In one such embodiment, the exercise device includes a trolley. The trolley includes at least one peg connected to the trolley, the at least one peg adapted to make contact with at least a portion of a user's foot. The exercise device also includes a shaft supported in an angled position to accommodate the trolley. The trolley is adapted to be pulled along the shaft towards the user by the at least the portion of the user's foot while the user is in a seated position.

## Claims

### Claim 1

An exercise device, comprising:
a trolley adapted to be pulled towards a user while the user is in a seated position, the trolley comprising:
at least two vertical plates with a first and a second side,
at least three wheels with a first and a second end, the first and the second end of the at least three wheels being connected to the at least two vertical plates, and
at least one peg connected to the trolley, the at least one peg adapted to make contact with at least a portion of the user's foot;
a shaft having a first and a second end, the shaft supported in an angled position accommodating the trolley; wherein the trolley is adapted to be pulled along the shaft towards the user while the user is in a seated position;
a substantially planar surface with a top surface connected to the shaft; and
a collapsible beam connected to the shaft, the collapsible beam supporting the shaft in the angled position while the collapsible beam is extended, and allowing the shaft to return to a collapsed position when the collapsible beam is folded to allow the exercise device to be stored in a substantially horizontal position.

### Claim 2 (depends on 1)

The device of claim 1, wherein:
the trolley structure is connected to the shaft by coupling means,
the least two vertical plates are positioned parallel to the shaft,
the at least three wheels are connected to the at least two vertical plates,
the at least three wheels span the shaft for rolling along the shaft, and the shaft is adapted with a plurality of openings to insert a locking pin allowing the trolley structure to start from a plurality of positions along the shaft.

### Claim 3 (depends on 1)

The device of claim 1, wherein at least one flexible cord is adapted to provide resistance to the trolley, the at least one flexible cord is connected to the trolley structure and a pulley at the first end of the shaft and to the second end of the shaft, the at least one flexible cord is adapted to use one of the at least three wheels on the trolley structure to act as a pulley.

### Claim 4 (depends on 1)

The device of claim 1, wherein the substantially planar surface includes:
a opening for holding onto the substantial planar surface;
a top surface, the top surface adapted for the user to sit in the seated position on the substantially horizontal surface; and
a bottom surface, the bottom surface connecting to the shaft.

### Claim 5 (depends on 1)

The device of claim 1, wherein the first end of the shaft connects substantially perpendicular to a first elongated base member and the shaft being connected to a second elongated base member, the second elongated base member supporting the shaft in an angled position.

### Claim 6 (depends on 1)

The device of claim 1, wherein the collapsible beam is adapted with a center joint to return the angled shaft to one of the angled position and one of the collapsed position, the collapsible beam is adapted with a locking slider device to prevent the collapsible bar form collapsing.
