## Abstract

An exercise device in accordance with the present disclosure may include a body having a first end and a second end, wherein a first end is configured to receive a handle attachment. The exercise device may also include a first connection component disposed at the second end of the body and configured to attach the exercise device to a first resistance component. A sensor may be coupled to the first connection component. Additionally, a processing circuit may be disposed in the body of the exercise device communicatively coupled to the sensor. The exercise device may include a rotatable display configured to be visible to a user as a user performs movements with the exercise device.

## Claims

### Claim 1

An exercise device comprising:
a body having a first end and a second end, wherein the first end is configured to receive a handle attachment;
a first connection component disposed at the second end of the body and configured to attach the exercise device to a first resistance component,
a sensor coupled to the first connection component;
a processing circuit disposed in the body of the exercise device communicatively coupled to the sensor; and
a rotatable display communicatively coupled to the processing circuit and configured to rotate along one or more axes and display information based on an output of the sensor,
wherein the processing circuit is programmed to:
detect a change in force during a movement of the exercise device;
subtract a hysteresis value from a target force once a detected force equals the target force;
while the detected force is above the target force less the hysteresis value, increment a time-under-tension clock; and
in response to detecting that the detected force falls below the target force less the hysteresis value, stop the time-under-tension clock.

### Claim 2 (depends on 1)

The exercise device of claim 1, wherein the first resistance component is an elastic band.

### Claim 3 (depends on 1)

The exercise device of claim 1, wherein the exercise device is programmed to:
receive an input of a desired target force;
detect, using the sensor, a change in force as a user changes a length of the first resistance component during a movement of the exercise device; and
provide the user with feedback, using the rotatable display, when the desired target force is detected.

### Claim 4 (depends on 1)

The exercise device of claim 1, wherein the exercise device is configured to be communicatively coupled to a mobile device, which is communicatively coupled to a second exercise device, wherein the exercise device is programmed to:
synchronize with the mobile device and the second exercise device;
receive a first command from the mobile device to set a first target force, wherein the mobile device sends a second command to the second exercise device setting the first target force; and
send an output of the sensor of the exercise device to the mobile device.

### Claim 5 (depends on 1)

The exercise device of claim 1, wherein the processing circuit is programmed to determine a first rate of force development (RFD) of a first movement performed with the exercise device, wherein the first RFD rate of force development (RFD) is independent of gravity.

### Claim 6 (depends on 5)

The exercise device of claim 5, wherein the processing circuit is programmed to determine the first rate of force development (RFD) for movements performed at multiple angles.

### Claim 7 (depends on 5)

The exercise device of claim 5, wherein the processing circuit is programmed to determine the first rate of force development (RFD) based on a change in force of the first movement over a length of time corresponding to a duration of the first movement.

### Claim 8 (depends on 5)

The exercise device of claim 5, wherein the processing circuit is programmed to:
determine the first rate of force development (RFD) based on a calculated rate of force development (RFD) for a plurality of sampling intervals during the first movement of the exercise device;
compare each calculated rate of force development (RFD) for the plurality of sampling intervals; and
select the first rate of force development (RFD) to be the calculated rate of force development (RFD) corresponding to a sampling interval with a highest calculated rate of force development (RFD).

### Claim 9 (depends on 1)

The exercise device of claim 1, wherein the rotatable display is rotatable to be visible to a user while using the exercise device.
