Introduction to the Duck Under

The duck under is a fundamental takedown technique with multiple finishing variations. This instructional guide covers two primary finishes: the mat finish and the claw lift. Proper execution requires precise grip control and body positioning throughout the movement.

Establishing the Collar Tie

The collar tie is the critical control point for executing an effective duck under. The instructor locks their hand on the opponent's neck while pinching the forearm inward to close the distance. This grip must remain tight throughout the entire technique to control the opponent's posture and facilitate the takedown.

The Monkey Grip and Initial Setup

The non-collar-tie hand establishes a monkey grip high on the opponent's tricep. Combined with the collar tie, these two points of control create the foundation for the duck under. The instructor positions themselves to step to the outside of the opponent's lead foot.

Executing the Level Change and Entry

The instructor steps to the outside while lifting the opponent's arm slightly to create minimal space. A controlled drop to the knee allows the practitioner to slip beneath the opponent's arm. Critical to this entry is maintaining a strong neck position by looking upward to prevent the opponent from trapping the head.

The Mat Finish: Spinning the Opponent Down

Once beneath the opponent's arm, the instructor spins on the knee while maintaining the collar tie grip. The practitioner's body weight and momentum drive the opponent down to the mat as a single, continuous motion. Upon reaching the mat, the instructor secures the opponent's back while maintaining collar control for subsequent submissions.

The Claw Finish: Level Change Without Kneeling

The claw finish variant keeps the practitioner on their feet throughout the initial duck under. Instead of dropping the knee, the practitioner performs a level change originating from the knees—never from the hips or neck. This variation maintains better positioning for the explosive lift that follows.

Achieving Perpendicular Positioning

After the level change, the practitioner transitions to a perpendicular angle relative to the opponent. Proper posture is maintained with bent knees, hips driven inward, and a straight back. The collar tie remains secured while the free hand prepares for the crotch grip.

The Crotch Grip and Explosive Lift

The free hand reaches as high as possible into the crotch area, gripping the inside of the thigh. The practitioner then explosively extends the legs and hips upward, lifting the opponent off the mat. Power is generated entirely from the legs and hips, never from the arms or back.

Completing the Claw Takedown

The lifted opponent is brought down to the mat in a controlled manner, completing the claw finish. Throughout the entire sequence, the collar tie grip remains engaged, and body positioning prioritizes proper mechanics and safety. Both finishes conclude with the practitioner in a dominant position for follow-up techniques.

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.
