Ude garami, or bent arm lock, can be done many ways and from different positions in Kodokan Judo. The opponent's arm can be bent upwards towards the head or down towards the legs. It often uses considerable twisting action that can injure the shoulder as well as the primary target of the elbow joint. This version is being demonstrated by Kenji Tomiki, 8th dan.

To achieve the strongest position to apply the armbar you must bend the opponent's elbow and seize his/her wrist with your hand so that the thumb side or your hand is closest to your opponent's elbow. You then reach under the opponent's elbow with your other arm and grab onto your own hand or wrist.

Udegarami can be done to apply pressure to the shoulder or the elbow. In Judo we try to achieve the armbar pressure on the elbow since it is the more efficient and effective version. The two key points that make ude garami work effectively against the elbow when you are in the basic udegarami position shown below are: 1) the arm should not be bent very far (90 degrees is too much), and 2) the elbow should be pulled towards the belt.
