1. A wearable device that monitors movement of a muscle group of a user who is wearing the device, said device comprising:
a housing;
a clip, wherein:
the clip is attached to the housing, and
the clip enables the wearable device to be coupled to a body part of the user, said body part being associated with the muscle group; and
a radio frequency (RF) sensor that is disposed in the housing, wherein:
the RF sensor is caused to oscillate at one of a plurality of available preselected frequencies,
the RF sensor is tuned to resonate when the RF sensor is located a preselected distance from the user's muscle group while the wearable device is clipped to the user's body part, and
as the user's muscle group moves closer or farther from the RF sensor based on the movement of the user's muscle group, a resulting waveform generated based on data from the RF sensor is modified, and the resulting waveform is usable to determine how the user's muscle group moved.
