## Abstract

A system can comprise a driving link, a first footplate link, a footplate, a pulley system, a second footplate link, and a handle. The driving link can rotate, to thereby cause the first footplate link to translate in a first direction. The translation of the first footplate link footplate in the first direction can cause the footplate and the second footplate link to translate in the first direction when the first footplate link translates in the first direction. The translation of the second footplate link in the first direction can transmit force to the handle via the pulley system, thereby causing the handle to translate in a second direction that is substantially opposite the first direction when the first footplate link the footplate, and the second footplate link are translating in the first direction.

## Claims

### Claim 1

A system comprising:
a driving link configured to rotate in a rotational direction;
a first footplate link in mechanical communication with the driving link, the first footplate link being configured to translate in a first direction in response to rotation of the driving link in the rotational direction;
a footplate in mechanical communication with the first footplate link such that the footplate is configured to translate in the first direction when the first footplate link translates in the first direction;
a pulley system comprising:
one or more pulleys; and
a belt in mechanical communication with the one or more pulleys;
a second footplate link in mechanical communication with the first footplate link and a first fixed belt position on the belt, wherein the second footplate link is configured to translate in the first direction when the first footplate link translates in the first direction, thereby causing the first fixed belt position to translate in the first direction and a second fixed belt position to translate in a second direction that is substantially opposite the first direction; and
a handle in mechanical communication with the second fixed belt position of the belt when the handle is in an engaged state such that when the footplate translates in the first direction, the handle translates in the second direction.

### Claim 2 (depends on 1)

The system of claim 1, wherein the second footplate link is in mechanical communication with the first footplate link via the footplate.

### Claim 3 (depends on 1)

The system of claim 1, wherein:
the rotational direction is a first rotational direction, and
the belt is configured to rotate in a second rotational direction when the driving link rotates in the first rotational direction, the second rotational direction being opposite the first rotational direction.

### Claim 4 (depends on 1)

The system of claim 1, wherein the handle is selectively detachable from the second fixed belt position, the handle being in a disengaged state when the handle is detached from the second fixed belt position.

### Claim 5 (depends on 4)

The system of claim 4, wherein the system further comprises an engagement system configured to transition the handle between the engaged state and the disengaged state.

### Claim 6 (depends on 5)

The system of claim 5, wherein the engagement system is configured to transition the handle between the engaged state and the disengaged state in response to receiving an instruction signal from a computing device.

### Claim 7 (depends on 5)

The system of claim 5 further comprising a handle restraining element configured to restrict translation of the handle when the handle is in the disengaged state.

### Claim 8 (depends on 7)

The system of claim 7 further comprising a rib attached to the handle and disposed between the handle and a handle attachment point configured to selectively engage the second fixed belt position, wherein the handle restraining element comprises a magnet configured to magnetically attach to the rib to thereby restrict translation of the handle when the handle is in the disengaged state.

### Claim 9 (depends on 1)

The system of claim 1, wherein the driving link is in mechanical communication with a motor.

### Claim 10 (depends on 1)

The system of claim 1 further comprising a carriage configured to translate along a carriage rail extending parallel to the first direction and the second direction, the carriage being in mechanical communication with the second footplate link to thereby stabilize translation of the second footplate link.

### Claim 11 (depends on 1)

The system of claim 1 further comprising:
a stride length track; and
a driving linkage connecting the driving link to the first footplate link, the driving linkage being configured to traverse along the stride length track, wherein a position of the driving linkage along the stride length track corresponds to a magnitude of translation for the first footplate link.

### Claim 12 (depends on 11)
