Suddenly Armbarred.... Please help

[wardancer]

Yes I am sitting high. My instructor yells at me if I dont

Sit on my feet, head high. Close and hold both collars with hand on sternum, other hand on his belt....

That's prolly why I've never been armbarred before: I used to lay on the opponent when in his guard.

Thanks for the advice!!!!!

Keep it coming, I can use every little bit.

If you put one arm on his sternum and sitting on your feet and if your opponent is in his back on a guard: you are asking for an arm bar!
try to break his guard, by putting both hands on his belt, then stack him by lifting both of his legs with both arms at the same time. If you leave one arm in the guard, and use only one arm to lift one leg , you are leaving yourselves open for a triangle and/or an arm-bar.
