A 5-minute video explaining and demonstrating how to do it.
I caught an awful flu earlier this year which had me incapable of doing anything other than sleeping or watching videos for two or three weeks. During that time I watched almost every Minibrute and Microbrute video on YouTube, and I was really surprised, because I did not find one video like this. I definitely saw some great videos, but nothing which addressed this fairly obvious use case. So I made this video.
