Basic Armbar From The Guard

Love your videos man... Nothing more important then these basics.

i just stick to basics. those are hard enought to master in a fight. real fight or grappling match. armbars like this i never usually get, except if it is a beginner.
i like my top position. always fight for it with basic hip heists and sweeps. i like catch as catch can. very basic stuff, but effective. and in jiu jitsu, i like the half guard stuff. got me out from the bottom most of the time.

Some of the details were a little sketchy...

When you set the foot on the hip (your left foot in the video), you didn't pinch the knee in to prevent him from pulling his arm out.

The right leg helps you rotate, but to set the arm bar really deep, you should be lifting your hips as you rotate while curling your heel toward your butt.

When you set the second leg, again, your hips should be shooting upward to really set that arm in nice and tight.

Crossing the ankles in that position is also counter productive. The pressure focus should be at the knees, not at the ankles. By keeping your feet uncrossed, you can focus on pinching your knees together to control the arm.

Also, to maintain a tight arm bar, you curl your heels toward you butt. When your ankles are crossed, you have only one anchor point on your opponent. When they're uncrossed, you have two. By having two anchor points, you can set each leg as deep as possible and then anchor by curling your heels toward your butt (while keep your hips elevated). Your right leg, the leg in the arm pit, can't set as deep as the leg that goes over the head, and by crossing your feet you are setting your second foot only as deep as the first foot allows.
