## Abstract

An exercise step and method of exercising a user's legs is disclosed. The exercise step includes a main body which has a substantially planar and horizontally oriented upper wall and a sloped wall extending from bottommost surface of the exercise step to the upper wall. In use, a user steps on the sloped wall with a heel portion of his or her foot and raises the heel portion such that a sole portion of his or her foot is supported by the upper wall.

## Claims

### Claim 1

An exercise step for placing directly on a floor, the exercise step configured for use with leg exercises, the exercise step comprising:
a body comprising:
a rectangular and horizontally oriented upper wall configured to be parallel with the floor that the exercise step is placed on, wherein the upper wall is configured to support a sole portion of a user foot;
a sloped wall extending lengthwise from a bottommost surface directly contacting the floor of the exercise step to the upper wall, the sloped wall being configured to support a heel portion of the user foot,
wherein a length of the upper wall is the same as a length of the sloped wall, and wherein each said wall has a surface area that is entirely and continuously planar;
a plurality of ribs that support the upper wall and the sloped wall,
wherein the bottommost surface defines a band channel disposed between a first set of ribs of the plurality of ribs and a second set of ribs of the plurality of ribs, and wherein the band channel is disposed directly below a transition from the sloped wall to the upper wall.

### Claim 2 (depends on 1)

The exercise step of claim 1, wherein the exercise step is a single-piece part.

### Claim 3 (depends on 1)

The exercise step of claim 1, wherein the upper wall is an uppermost surface of the exercise step.

### Claim 4

A method of exercising a user's legs, the method comprising the steps of:
placing two exercise steps side by side in a spaced apart arrangement;
each exercise step comprising:
rectangular and horizontally oriented upper wall configured to be parallel with the floor that the exercise step is placed on, wherein the upper wall is configured to support a sole portion of a user foot;
a sloped wall extending lengthwise from a bottommost surface directly contacting the floor of the exercise step to the upper wall, the sloped wall being configured to support a heel portion of the user foot,
wherein a length of the upper wall is the same as a length of the sloped wall, and wherein each said wall has a surface area that is entirely and continuously planar;
a plurality of ribs that support the upper wall and the sloped wall,
wherein the bottommost surface defines a band channel disposed between a first set of ribs of the plurality of ribs and a second set of ribs of the plurality of ribs, and wherein the band channel is disposed directly below a transition from the sloped wall to the upper wall;
engaging a band in the band channels of the two exercise steps in the spaced apart arrangement;
stepping on the sloped wall with the heel portion of the user foot;
manually pulling on the band; and
raising the heel portion such that the sole portion of the user foot is supported by the upper wall.
