The oldest movement in ground defense: create hip space, and every escape becomes possible.
Create the angle and space needed to stand back up or move to a safer position.
From the frame, post your top foot flat on the ground and drive off it. The push is horizontal: you are creating space, not standing up.
As the foot pushes, your hips travel backward and away in an arc. Shoulders stay planted; only the hips move.
The gap is your window. It is enough to reinsert a leg, begin a stand-up, or fire a kick. Chain three shrimps if space allows; each one buys inches, and three of them buy the distance to your feet.
