Introduction to the Duck Under

The duck under is a fundamental grappling technique with two primary finishing methods: a direct mat takedown and an elevated finish using the claw. Both variations begin with identical setup and grip work before diverging at the execution phase.

Establishing the Collar Tie

The collar tie is the critical control point for the duck under, as it provides leverage to drag the opponent to the mat. The grip requires a locked hand with the forearm pinched tightly against the opponent's neck, creating a closed, compact position rather than an extended hold.

The Monkey Grip and Arm Control

The non-controlling hand establishes a monkey grip high on the opponent's tricep. This two-point control system—collar tie and tricep grip—creates the foundation for both finishing variations and prevents the opponent from escaping the position.

Creating the Window and Head Position

As the practitioner steps to the outside of the opponent's base, a slight lift of the arm creates enough space to execute the duck under. Critically, the head must remain in a strong, upright position throughout to prevent the opponent from trapping it.

Mat Finish: Knee Drop and Spiral

The first variation concludes with a knee drop to the mat while spinning on the planted leg, using body momentum and weight to drive the opponent down. The collar tie remains locked throughout to control the opponent's neck and facilitate back control on the mat.

Claw Finish: Level Change and Positioning

The claw finish keeps the practitioner on their feet during the initial phase, requiring only a level change from the knees rather than a full knee drop. The arm must remain pinched against the shoulder like holding a telephone to prevent the opponent from escaping.

Perpendicular Positioning and Posture

After the level change, the practitioner rotates to become perpendicular to the opponent while maintaining proper posture: bent knees, engaged hips, and a straight back. This positioning creates the optimal mechanical advantage for the explosive lift portion of the technique.

The Claw Grip and Explosive Finish

The free hand secures a grip on the inside of the opponent's thigh as high as possible in the crotch area. The finish is driven entirely through leg and hip extension, never relying on arm or back strength, resulting in a powerful upward lift before slamming the opponent to the mat.

If not, your opponent can attempt a front headlock or guillotine choke - Make sure to get perpendicular to your partner or all the way towards his back.
