The omoplata can be applied from the guard, by placing one leg under the opponent's armpit and turning 180 degrees in the direction of that leg, so that the leg moves over the back of the opponent and entangles the opponent's arm. By controlling the opponent's body and pushing the arm perpendicularly away from the opponent's back, pressure can be put on the opponent's shoulder. It is also possible to put pressure on the elbow joint by bending the leg entangling the arm, and twisting it in a specific manner. Though an effective lock, it is more difficult than other armlocks to successfully apply. The technique called a monoplata is a similar armlock that resembles juji gatame or spiderweb position yet has a mechanism like an omoplata.
