Under mount

Under mount is a descriptive name for the mount bottom position — naming the defensive position beneath a mounted opponent.

Etymology. “Under mount” frames the position from the pinned player’s perspective: caught beneath full mount. The label is the bottom counterpart to the top mount.

Mechanics. Escape turns on hip mobility: the bridge and the shrimp are the engine, lifting and angling the hips to create the space to recover a knee or roll the mount. Without hip movement there is no room to work, so restoring the hips’ ability to bridge and shift is the first requirement of every mount escape.

Cross-reference. “Pinned under mount” is a sibling alias. Full mechanical coverage on Mount — Bottom.
