Need help escaping head lock on ground

[Cyph]

You need to establish yourself a base, so with the hand furthest away from his head, post in on the ground. Then with the other hand, post it on his face and push. As he realeases his grip, make sure you keep the underhook on his arm, grab your own wrist on the other hand, move your hips forward and keep them over the guy as you fall back into the armbar.

I think I can picture that. Thanks for the tips.
