Waki-gatame (脇固め, 'armpit hold') is a standing or ground armlock where the opponent's extended arm is trapped under the attacker's armpit, and downward pressure is applied to hyperextend the elbow. [1],[2] The attacker catches the opponent's wrist or forearm, tucks it under the armpit, and uses body weight or a dropping motion to straighten and hyper-extend the elbow against the armpit as a fulcrum. [1] Waki-gatame is notable for its speed — it can be applied in a single explosive motion during standing exchanges, making it one of the fastest arm locks. [1],[3]
История и происхождение
Waki-gatame is a classical Kodokan Judo kansetsu-waza that is somewhat restricted in judo competition due to its speed and injury potential — dropping into waki-gatame while standing is considered dangerous. [2],[3] In aikido, a similar armpit-fulcrum arm lock is practiced as ikkyo or variations thereof. [1] The technique appears in self-defense and law enforcement systems worldwide. [1]

Биомеханический механизм
Primary Action — Hyperextension of the elbow joint — the hips drive upward against the posterior humerus while controlling the wrist
Joints Involved — Elbow (extension beyond normal ROM), wrist (stabilized), shoulder (isolated and controlled)
Force Vector — Posterior-to-anterior force on the upper arm with fixed distal anchor at the wrist creates a lever arm across the elbow
Leverage Principle — Hips act as the fulcrum — the longer the lever (full arm extension), the less force needed to hyperextend
Позиция и вход
From top position — Isolate the arm, control the wrist, and apply hyperextension pressure against the elbow using body positioning
From guard — Secure wrist control, pivot to create the angle, and apply elbow hyperextension from the bottom position

Waki-gatame is a traditional elbow lock found across judo, jiu-jitsu, and ninjutsu curricula, though its application and effectiveness vary by context. Robert Silas (Aiki_and_Jiu) provides the most detailed technical breakdown, explaining that waki-gatame begins by stepping behind or to the side of an opponent, throwing the arm over the top and squeezing tightly in the armpit to create a standing joint lock. He notes it is banned in judo tournaments as a standing lock due to safety concerns, but remains viable in self-defense and ground positions. Silas emphasizes that against trained opponents in randori, the technique's standing form is rarely effective because practitioners instinctively protect their arms; instead, he advocates using the initial waki-gatame attempt to create kazushi (off-balance), allowing transitions into sacrifice throws or ground pins. He details ground variations where the shoulder is pinned with the opponent's palm facing upward, requiring angle changes and forward pressure to force submission. Yossi Sheriff (AKBAN Ninjutsu) demonstrates waki-gatame as part of a combination flowing into ura oni kudaki, stressing dangerous arm mechanics that can fracture the head or break the eardrum if applied with force, and emphasizing controlled dojo practice versus street applications. Sheriff highlights proper leg positioning and immobilization angles as critical to safe execution. The Judo Way of Life video provides minimal technical content beyond categorizing the technique within katame waza (grappling techniques).

✓Waki-gatame (armpit armlock) traps the opponent's arm under the attacker's armpit and hyperextends the elbow using body weight and rotation — one of judo's most effective standing armlocks (Kashiwazaki, Osaekomi, 1997)
✓The mechanic: the opponent's wrist is secured while their elbow is positioned against the attacker's armpit — the attacker then drops, rotates, or arches to hyperextend
✓Waki-gatame is classified as a standing armlock: it is typically applied during grip fighting or when the opponent extends an arm for a throw attempt
✓The technique was banned in judo competition (IJF rules) due to the speed and severity of application — it hyperextends the elbow explosively
✓In BJJ, MMA, and catch wrestling, waki-gatame remains a highly effective technique — particularly during scrambles and transitions
✓The armpit provides a tight, secure fulcrum: the arm is locked in place with nowhere to escape while the body weight creates the extension force
✓Waki-gatame has numerous entries: from grip fighting, from failed throws, from standing clinch, and from ground transitions where the opponent reaches out
Типичные ошибки
!Applying explosively without control — waki-gatame can break the elbow instantly; always apply with control in training
!Not securing the wrist before committing — the wrist must be locked against the chest before the drop or rotation
!Attempting when the arm is bent — the arm must be relatively straight for the armpit to serve as an effective fulcrum
!Not using body weight — waki-gatame finishes through body weight and gravity; arm strength alone is insufficient
!Dropping without controlling the opponent's base — if the opponent follows you down in a controlled way, the lock weakens
!Not transitioning to the ground finish — if the standing waki-gatame doesn't tap, follow to the ground and continue
!Applying from the wrong angle — the arm must be aligned with the armpit; an angled arm can rotate and escape

Заметки
Waki gatame (armpit arm lock) is a Kodokan judo technique — the attacker traps the opponent's arm under their armpit and applies pressure against the elbow. One of the nine officially recognized kansetsu-waza. Can be applied standing or on the ground. (Kano, Kodokan Judo)
Часто задаваемые вопросы
How do you use kuzushi (balance breaking) to set up waki-gatame?
According to Robert Silas, pulling your opponent forward creates kazushi—they naturally sit back in response. If you push them back, they sit forward. By pulling forward with an overhand grip during the initial arm throw, you break their balance and create the opportunity to sit behind them for the technique.
What should I do if my opponent doesn't leave their arm turned over?
Robert Silas explains that against a trained opponent who keeps their arm defended, you should abandon trying to enter into a walking atami and instead use the kuzushi to sit behind them, then work to isolate and control the arm from that position.
How do you finish waki-gatame once you've isolated the arm?
Robert Silas teaches that you should block your opponent's face and drop your shoulder while scooting your foot out to isolate the arm, then take a big step while maintaining shoulder pressure. You can finish by dropping your weight on their shoulder with your triceps across their face, or transition to chokes or other submissions.
