## Abstract

Described herein are examples of resistance exoskeleton devices that include a modular rigid body configured to house resistance bands. The rigid body comprises a rigid member to support the exerciser's arm and house the resistance bands, an adjustable shoulder rest, and a support arm to connect the tricep rest to the shoulder rest. The device includes an interchangeable handle, a resistance band roller, and interchangeable resistance bands. The device features adjustment points, including support arm pins, quick-release locking pins, and thumb screws, to allow for customization and is configured to hold at least one low-friction pivot point to provide smooth motion between at least two modules during exercises.

## Claims

### Claim 1

A device, comprising:
a modular body configured to house a resistance band suitable for strength training exercises, wherein the modular body comprises:
a rigid arm member configured to support an arm of an exerciser,
a tricep rest member moveably coupled to a first end of the rigid arm member,
a shoulder rest member coupled to the tricep rest member and configured to support a shoulder of the exerciser during exercises and prevent the tricep rest member from rotating under tension, wherein the shoulder rest member is adjustable to accommodate different shoulder sizes and positions;
a handle member configured to provide a gripping point for the exerciser during the exercises, wherein the handle is interchangeable with different handles for various exercises; and
a plurality of adjustment points to allow for customization and adjustment of the device to suit different exercises and user needs.

### Claim 2 (depends on 1)

The device of claim 1, wherein the rigid arm member further comprises:
a first channel formed on a rear side of the rigid arm member, wherein the first channel houses a least a first portion of the resistance band; and
a first connection member configured to couple to a first side of the resistance band.

### Claim 3 (depends on 2)

The device of claim 2, wherein the first connection member comprises a first removable pin that extends from a first side of the rigid arm member to a second side of the rigid arm member through the first channel.

### Claim 4 (depends on 2)

The device of claim 2, wherein the tricep rest member further comprises:
a second channel formed on a rear side of the tricep rest member, wherein the second channel houses a least a second portion of the resistance band; and
a second connection member configured to couple to a second side of the resistance band.

### Claim 5 (depends on 4)

The device of claim 4, wherein the second connection member comprises a second removable pin that extends from a first side of the tricep rest member to a second side of the tricep rest member through the second channel.

### Claim 6 (depends on 2)

The device of claim 2, wherein the rigid arm member further comprises:
a resistance band roller positioned with the first channel, wherein the resistance band roller provides a pivot point for the resistance band during exercises, reducing friction and wear on the band.

### Claim 7 (depends on 1)

The device of claim 1, wherein the modular body further comprises:
a support arm member configured to connect the tricep rest member to the shoulder rest member, wherein the support arm member is adjustable and is positionable on either side of the device to accommodate different exercises and preferences.

### Claim 8 (depends on 1)

The device of claim 1, wherein the resistance band comprises a plurality of resistance bands that are interchangeable, each of the plurality of resistance bands having a different strength to accommodate user preferences.

### Claim 9

A device, comprising:
an arm rest configured to support an arm of an exerciser;
a tricep rest moveably coupled to a first end of the arm rest;
a shoulder rest coupled to the tricep rest by a support bar;
at least one resistance band coupled between the arm rest and the tricep rest; and
a handle movably coupled to a second end of the arm rest by an adjustment mechanism, wherein the adjustment member allows the handle to be selectively moved relative to the arm rest.

### Claim 10 (depends on 9)

The device of claim 9, wherein the adjustment mechanism comprises:
a bracket moveably coupled to slide channels formed within sides of the arm rest; and
a locking pin coupled to the bracket and configured to selectively engage with a positioning channel formed in the arm rest.

### Claim 11 (depends on 10)

The device of claim 10, wherein the positioning channel comprises a series of locking positions aligned along a long axis of the arm rest, and wherein the locking pin is selectively engaged with the series of locking positions to change a position of the handle.

### Claim 12 (depends on 9)

The device of claim 9, wherein the arm rest further comprises:
a first channel formed on a rear side of the arm rest, wherein the first channel houses a first portion of the at least one resistance band;
a first connection channel formed in a first sidewall of the first channel; and
a second connection channel formed in a second sidewall opposite the first sidewall.

### Claim 13 (depends on 12)

The device of claim 12, wherein the tricep rest further comprises:
a second channel formed on a rear side of the tricep rest, wherein the second channel houses a second portion of the at least one resistance band;
a third connection channel formed in a first sidewall of the second channel; and
a fourth connection channel formed in a second sidewall opposite the first sidewall.

### Claim 14 (depends on 13)

The device of claim 13, wherein the at least one resistance band further comprises:
a first connection bar;
second connection bar; and
an elastic band coupled between the first connection bar and the second connection bar, wherein the elastic band provides resistance during exercises.

### Claim 15 (depends on 14)

The device of claim 14, wherein:
the first connection bar is coupled to the first connection channel and the second connection channel;
the second connection bar is coupled to the third connection channel and the fourth connection channel; and
tension of the elastic band holds the first connection bar in the first connection channel and the second connection channel, and holds the second connection bar in the third connection channel and the fourth connection channel.

### Claim 16 (depends on 9)

The device of claim 9, wherein the at least one resistance band comprises a first resistance band having a first elastic strength and a second resistance band having a second elastic strength different from the first elastic strength.

### Claim 17 (depends on 9)

The device of claim 9, further comprising:
a roller positioned between the at least one resistance band and the arm rest, wherein the roller provides a pivot point for the at least one resistance band during exercises.

### Claim 18

A system, comprising:
an arm rest configured to support an arm of an exerciser;
at least one interchangeable shoulder rest coupled to arm rest;
at least one interchangeable resistance member configured to provide resistance during exercises;
