This was something that I wanted to just crank out to feel like I could make a decent looking motion project in a few hours. All I really did was trace the arm from a picture, and eyeball the muscle movements frame by frame.
The animation was attached to a Spotify playlist that I posted on Instagram. (You can find the Instagram post here) The playlist constitutes a musical style that transcends genres, focusing on fast, fun, generally electronic-heavy fist-pumpers.
