Funkbuster
https://youtu.be/w52Mk2uDJAw
My Improv teacher Tara taught me this as a way to “shake off the day” before performing or practicing.
I find it to be a weird, fun, and quick exercise to get myself out of a funk, too. Tara never named this, so I’m taking a liberty here by naming it The Funkbuster, but that’s better than “the crazy arm thing Tara taught me” which I was calling this in my head.
