Gluteus medius

The side-hip muscle that keeps the pelvis level whenever you stand on one leg.

The gluteus medius (with the smaller gluteus minimus beneath it) sits on the outer hip, running from the pelvis to the top of the thigh bone. Its main job is hip abduction — moving the leg out to the side — and, more importantly in daily life, stabilizing the pelvis: every step you take, it stops the opposite side of the pelvis from dropping.

One-legged yoga poses are gluteus medius auditions. In Tree, Warrior III and Half Moon, the standing leg's medius is what keeps the pelvis level rather than sagging toward the lifted side. A pelvis that will not stay level is usually this muscle asking for strength work, which standing balances deliver in small, honest doses.
