This class was all about armbars. First we looked at a basic armbar from guard, but more importantly talked about how to finish that armbar when your opponent stacks you. The following video is pretty good despite the fact that I have no idea what he is saying.
Next we talked about an armbar from top turtle. You will notice a similar finishing position to the technique above. We recently went over this technique in Sambo class, so here is that same video again.
Last we looked at a 'falling armbar' that I prefer over a true flying armbar. We did this both kneeling and standing.
As a bonus, here is an old video of me hitting this technique back in my blue belt days.
