Hey! I am working out at a vale tudo school over the summer, and though I hold my own on the ground, I am having some trouble adjusting to the no-gi game. Specifically, I am having trouble with armbars from the guard, as I cannot seem to get a decent grip on the wrist with all the sweat. This is causing me tremendous problems, and weakens my guard considerably. Since we do not usually wear gloves, the only way I have figured out is to overhook my opponent's arm into my armpit and slide my hips around from there (which is difficult and requires a lot of flexibility). Any suggestions for other things I should try? Thanks!
