Straight Armlock
SubFamily腕挫(Ude-hishigi)
TraditionalTranslation: arm crush (straight)
Overview
The straight armlock hyperextends the elbow by controlling the wrist and applying force against the back of the fully extended arm. [1],[2] Unlike the armbar which uses hip elevation from a perpendicular position, the straight armlock can be applied from various angles using the hands, forearms, or body to press against the elbow while the wrist is pulled. [1] Common entries include from side control (Americana position with the arm straightened), from mount, or as a standing arm lock in self-defense contexts. [1],[3]
History & Origin
Straight arm locks appear across virtually every grappling tradition, from Japanese jujutsu to catch wrestling to European folk wrestling. [1],[2] In judo's kansetsu-waza, the straight extension of the elbow is the foundational principle underlying all arm locks. [2],[3] The technique is also widely used in law enforcement and military restraint methods. [1]
Effectiveness
Lineage
Juji-gatame is the foundational armlock in judo, dating to the Kodokan's original kansetsu-waza curriculum. [1]

Biomechanical Mechanism
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
Position & Entry
From mount — Control opponent's wrist, pivot to S-mount or perpendicular position, swing leg over the head, lean back and extend hips
From S-mount — Already in position with knee high under armpit, secure the arm, fall back and extend for the armbar
Variants
Standard armbar — hips drive upward against the extended arm with legs clamping the shoulder
Belly-down armbar — rolling to face the mat to prevent the opponent from stacking
S-mount armbar — transitioned from S-mount position for tighter control before falling back
Spinning armbar — rapid pivot from guard or side to catch the arm during transition

The straight armlock is a fundamental elbow joint-lock submission that isolates and hyperextends the opponent's arm by controlling the elbow fulcrum while pinning the wrist. BJJ Fanatics' Andre Galvao emphasizes the technique's utility as a transition from the Americana grip, detailing precise hand positioning where the attacker turns the opponent's thumb upward, presses the wrist toward the mat, and lifts the elbow while maintaining frame control—noting that leg placement is critical to prevent the opponent from rotating away. Knight Jiu-Jitsu's Eli provides comprehensive mounted armbar fundamentals, stressing the S-mount position as the optimal setup, with particular attention to the compression component where leg squeeze combines with leverage, and emphasizing that hip thrust should occur only after secure leg compression is established. Both instructors agree on the importance of preventing escape through positional control and compression, though Galvao focuses on side-control variations with leg-frame techniques while Eli details the mounted transition sequence. TRITAC Martial Arts introduces standing straight armlock variations (udi gatami and related techniques), presenting these as breaking techniques in self-defense contexts where violence and speed are essential to snap the elbow quickly, contrasting with sport jiu-jitsu's submission approach. All three instructors converge on the principle that proper elbow positioning and forearm blade contact at the elbow joint create the mechanical advantage necessary for effective submission.

✓The straight armlock extends the opponent's arm against the elbow joint in a linear direction — applying force along the arm's natural line rather than across it (Kashiwazaki, Osaekomi, 1997)
✓Unlike the cross-body armbar, the straight armlock can be applied while staying in a dominant position (mount, side control) without transitioning to a perpendicular angle
✓The straight armlock uses the attacker's body weight and arm leverage: both hands control the opponent's wrist while the body drives downward — the elbow hyperextends against the attacker's thigh, hip, or chest
✓The key advantage of straight armlocks: the attacker maintains top position throughout — there is no risk of losing position during the submission attempt
✓Common straight armlocks: Americana (ude-garami), kimura (gyaku ude-garami), and top wrist lock — each applies extension or rotation from a dominant position
✓The straight armlock principle applies across positions: from mount, the weight drops onto the extended arm; from side control, the shoulder pins while the arms extend
✓Catch wrestling's 'double wrist lock' system extensively uses straight armlock mechanics (Gotch, Conditioning and Catch-As-Catch-Can Wrestling, 1908)
Common Mistakes
!Not fixing the shoulder — the opponent's shoulder must be pinned to the ground or controlled; a mobile shoulder allows the arm to rotate and escape
!Pulling up instead of pressing down — straight armlocks work by driving the attacker's weight into the arm, not by lifting it
!Not isolating the arm from the body — the arm must be separated from the torso; if the elbow stays tight to the body, the armlock cannot be applied
!Attempting from an unstable position — maintain top control throughout; if the position is compromised, abandon the lock attempt
!Not controlling the wrist — both hands must secure the wrist; a free wrist allows the opponent to bend and escape
!Using the same straight armlock every time — vary between Americana, kimura, and straight extension to keep the opponent guessing
!Applying with the wrong fulcrum position — the elbow must be over a solid surface (thigh, hip, chest) to create the extension force

Notes
The straight armlock (ude-hishigi in aikido) appears in 28 passages across 3 books. The Principles and Practice of Aikido (Yamada & Macintosh) describes it as 'the first of the four basic elbow techniques, hiji-waza, applied in the form of a straight armlock, ude-hishigi.' Applied by straightening the arm against a fulcrum. (3 books; Yamada & Macintosh, Principles and Practice of Aikido)
Frequently Asked Questions
How do I transition from an Americana to a straight armlock?
Andre Galvao teaches that when your opponent tries to escape the Americana by turning, you can follow their arm and transition to the straight armlock by stapling their arm in place and attacking from that position.
What's the most important contact point when applying a straight armlock?
TRITAC Martial Arts emphasizes that when using a blade or forearm, you should always connect to the inside of the elbow and focus on pushing the elbow forward to create the breaking sensation.
What position should I be in to hit a straight armlock effectively?
Knight Jiu-Jitsu teaches that the S-mount position is the typical way to catch a straight armlock effectively, where your legs are curved tight and you hug the opponent's arm using body weight rather than arm strength.
When finishing a straight armlock from S-mount, what's a common mistake to avoid?
Knight Jiu-Jitsu points out that you should cover the opponent's head before your hips hit the ground, and avoid thrusting your hips through the elbow too early—instead, establish compression first to prevent them from escaping via hitchhiker or other methods.
