## Abstract

The power stride apparatus and method therefor is directed to training the quads and gluts. In one embodiment, the apparatus comprises rotatable pedal assemblies having articulating pedals which may be engaged by a user's feet. The apparatus may include a seat to support the user. Resistance devices, such as one or more springs, may attach to the pedal assemblies to provide resistance to the movement of the pedal assemblies and to return to pedal assemblies to their initial position. The user may push the pedal assemblies and resist the return of the pedal assemblies thus training the user's quads and gluts. The articulating pedals allow training to be focused on the quads and gluts and provide a safer workout for the user. In some embodiments, return mechanisms may be used to allow the articulating pedals to follow the rotation of the user's foot during training.

## Claims

### Claim 1

A power stride apparatus comprising:
a frame;
a first pedal assembly rotatably attached to the frame;
a second pedal assembly rotatably attached to the frame and capable of rotatable movement independent from the first pedal assembly;
a seat configured to support a user facing the first and second pedal assemblies;
a first resistance device attached to the frame and the first pedal assembly, the first resistance device configured to resist rotational movement of the first pedal assembly relative to the frame, and including a first weight stack with variable weight setting supported upon a first base, a first lifting mount connected to the first weight stack, and a first elastic element connected between the first base and the first lifting mount; and,
a second resistance device attached to the frame and the second pedal assembly, the second resistance device configured to resist rotational movement of the second pedal assembly relative to the frame, and including a second weight stack with variable weight setting supported upon a second base, a second lifting mount connected to the second weight stack, and a second elastic element connected between the second base and the second lifting mount.

### Claim 2 (depends on 1)

The power stride apparatus of claim 1, wherein the elastic elements of the first and second resistance devices are springs.

### Claim 3 (depends on 1)

The power stride apparatus of claim 1, wherein the resistance of the first resistance device to rotational movement of the first pedal assembly may be different from the resistance of the second resistance device to rotational movement of the second pedal assembly.

### Claim 4 (depends on 1)

The power stride apparatus of claim 1, wherein the variable weight setting of the first weight stack is independent from the variable weight setting of the second weight stack.

### Claim 5 (depends on 4)

The power stride apparatus of claim 4, wherein weight settings for first pedal assembly may be different from the weight setting for the second pedal assembly.

### Claim 6 (depends on 1)

The power stride apparatus of claim 1, wherein the first and second weight stacks each have tops and the first and second lifting mounts are connected to the tops of the first and second weight stacks.

### Claim 7 (depends on 1)

The power stride apparatus of claim 1, wherein the first and second weight stacks each have tops and the first lifting mount is connected to the top of the first weight stack, and the second lifting mount is connected to the top of the second weight stack.

### Claim 8 (depends on 1)

The power stride apparatus of claim 1, wherein the first pedal assembly is attached to the first resistance device by a cable, and the second pedal assembly is attached to the second resistance device by a cable.

### Claim 9 (depends on 1)

The power stride apparatus of claim 1, wherein the position of the seat on the frame is adjustable.

### Claim 10 (depends on 1)

The power stride apparatus of claim 1, wherein each weight stack is configured as a forty-five degree angle to the seat.

### Claim 11 (depends on 7)

The power stride apparatus of claim 7, wherein the elastic elements are aligned along a narrow, non-face side of each weight stack, with the first and third elastic elements on opposite side of the first weight stack, and with the second and fourth elastic elements on opposite sides of the second weight stack.

### Claim 12 (depends on 1)

The apparatus of claim 1 further comprising one or more handles located adjacent to the seat.

### Claim 13

A power stride apparatus comprising:
a frame;
a first elongated pedal assembly with first end attached to a pedal and second end rotatably attached to the frame;
a second elongated pedal assembly with first end attached to a pedal and second end rotatably attached to the frame and capable of rotatable movement independent from the first pedal assembly;
a seat configured to support a user facing the first and second pedal assemblies, the seat adjustably configured to the frame to adjust the distance between the user and the pedals;
a first resistance device attached to the frame and the first pedal assembly, the first resistance device configured to resist rotational movement of the first pedal assembly relative to the frame, and including a first weight stack with variable weight setting supported upon a first base, a first lifting mount connected to the first weight stack, and two elastic elements connected between the first base and the first lifting mount on opposite sides of the first weight stack; and,
a second resistance device attached to the frame and the second pedal assembly, the second resistance device configured to resist rotational movement of the second pedal assembly relative to the frame, and including a second weight stack with variable weight setting supported upon a second base, a second lifting mount connected to the second weight stack, and two elastic elements connected between the second base and the second lifting mount on opposite sides of the second weight stack.
