One-Armed Ideas?

Hi all, I'm forced to rest my left (non-dominant) arm totally for about a month due to biceps tendinitis. Wanted to pick your brains as to some one-armed moves I can work on using only my right arm. I can do almost any twirl one-handed, and am working on reverse grab a good bit as it has never been super strong for me. What else can I do with one arm--besides dancing and transitions? Ideas?? Thanks! 🙂
