I know it is a little old, but I had posted this video on my youtube channel a long time ago, and I couldn’t not post it on my blog too.
In the World’s 2014 one of my teammates Marcos Tinoco, a brown belt at that time, used the cartwheel armbar in one of his matches on his way to becoming the brown belt middle weight World Champion.
Marcos was competing against another very tough Alliance competitor, and he was working to pass the guard. Instead of just trying to pass Marcos did a cartwheel armbar, getting the submission with this very tight submission.
I made a video with Marcos where he taught us exactly how he did it.
I hope you guys enjoy it.
