Compression locks are submission techniques that crush muscle tissue against bone, causing intense pain through deep tissue compression rather than joint hyperextension or vascular restriction. [7] The most common compression locks target the biceps (biceps slicer/biceps crush), the calf (calf slicer/calf crush), and the forearm. The mechanism involves trapping a limb across a fulcrum — typically the attacker's shin, forearm, or wrist — and then forcing the opponent's limb to fold, wedging the fulcrum deeper into the muscle belly against the underlying bone. [9] Compression locks can also indirectly stress the adjacent joint: a biceps slicer simultaneously threatens the elbow, and a calf slicer can hyperextend the knee. [9] In competition, compression locks occupy a contested regulatory space: IBJJF rules permit the biceps slicer only at brown and black belt level and the calf slicer at brown belt and above [1]; ADCC and most no-gi events permit all compression locks; judo prohibits them entirely. In MMA under Unified Rules, compression locks are legal.
История и происхождение
Compression locks have been practiced in various grappling traditions but were historically less codified than joint locks and chokes. In sambo, the calf slicer has been a standard competition technique since the sport's formalization in the 1930s, reflecting sambo's emphasis on leg attacks. [2],[3] Brazilian Jiu-Jitsu initially treated compression locks as secondary techniques, but their effectiveness in competition — particularly the calf slicer as a counter to the berimbolo and other inversions — has led to increased adoption since the 2010s. [8] The biceps slicer gained prominence in modern no-gi grappling as a complement to armbar attacks, used when the defender straightens the arm to escape the standard armbar. [9]

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

✓Compression locks (muscle crushers) cause submission by compressing muscle tissue against bone — creating intense pain without directly attacking a joint (Danaher, Leg Lock Anthology, 2019)
✓The primary compression locks target the calf (calf slicer/calf crusher) and the bicep (bicep slicer) — areas where muscle can be trapped against bone
✓Compression locks work by inserting a fulcrum (shin, forearm, or knee) behind the target limb and then folding the limb against it — crushing the muscle
✓These submissions are legal in most advanced grappling rule sets (brown/black belt BJJ, ADCC, MMA) but often restricted at lower levels due to injury risk
✓Compression locks frequently appear as secondary attacks: a failed armbar can transition to a bicep slicer, a failed heel hook can become a calf slicer
✓The pain from compression locks is immediate and intense — there is less warning than with joint locks, which makes tapping early essential
✓Compression locks can cause compartment syndrome in severe cases — the trapped muscle swells within its fascia, creating a medical emergency
Типичные ошибки
!Applying compression locks explosively — the intense pain requires controlled, gradual application to allow the training partner time to tap
!Ignoring the joint lock threat within the compression — many compression positions also threaten the knee or elbow; be aware of both dangers
!Not securing the position before applying compression — like all submissions, positional control precedes the finishing mechanism
!Using compression locks as primary attacks — they are most effective as transitions from failed joint locks, not as first-option submissions
!Applying without understanding the injury mechanism — compression locks can cause serious muscle damage; understand the anatomy
!Not training compression lock defences — recognise the setup early and retract the limb before the fulcrum is inserted
!Assuming compression locks are 'pain only' — they can cause real structural damage to muscle tissue and compartments

Arm Compression
СемействоArm compression techniques (biceps slicers and forearm crushes) work by trapping the opponent's arm over a fulcrum — typically the attacker's wrist, forearm, or shin — and forcing the arm to fold, crushing the biceps or forearm muscle against the underlying bone. [1,2] The biceps slicer is the most common arm compression, applied by placing a forearm or shin in the crook of the opponent's elbow and pulling the wrist to close the angle, compressing the biceps against the radius and ulna. Arm compressions can also indirectly hyperextend the elbow, making them effective combination threats with armbars. [3] In IBJJF competition, arm compressions (biceps slicers) are only legal at brown and black belt levels; in ADCC and MMA, they are unrestricted.

Calf Slicer Choke
СемействоThe calf slicer (also called calf crush or calf compression) works by placing a hard fulcrum — typically the shin or forearm — behind the opponent's knee and folding the lower leg back, crushing the calf muscle between the fulcrum and the femur. [1,2] The technique generates intense pain through deep muscle compression and can also hyperextend the knee joint. Calf slicers are commonly entered from leg entanglement positions, back control (particularly when an opponent tries to clear hooks), and as counters to berimbolo and inversion-based guard passes. [3] In IBJJF competition, calf slicers are legal only at brown belt and above; in ADCC and MMA, they are unrestricted. The calf slicer has become increasingly important in modern no-gi grappling as leg lock games have expanded.

Spladle
СемействоThe Spladle is a unique submission hold that originates from wrestling and functions as a compression lock/stretch submission — the attacker traps the opponent's head and one leg together, then forces the other leg apart, creating a painful split that attacks the groin, hip, and lower back. [1] In wrestling, the spladle is primarily used as a pinning combination (trapping the head and leg together while driving the opponent's shoulders to the mat), but in submission grappling and MMA, it has been adapted as a submission hold where the forced split creates enough pain and joint stress to force a tap. [1,2] The spladle is entered from front headlock position or when the opponent attempts a single-leg takedown — the attacker threads their arm between the opponent's legs to capture the far leg while maintaining head control, creating the head-and-leg trap. [2,3] While not a common submission in modern competition, the spladle has a dedicated following and has been used successfully in MMA by fighters like Ben Askren. [3]

Заметки
Compression locks use bone-on-muscle pressure to create pain — bicep slicers, calf slicers, chest compression. Banned in IBJJF below brown belt. Less common than joint locks but extremely effective when applied. Bicep slicer appears in 8 passages across 2 books. (2+ books; IBJJF Rules v6.0; BJJ instructionals)
Часто задаваемые вопросы
What's the biggest mistake people make when trying to set up a compression lock?
According to Hudson Combat Academy, never grab the opponent's actual foot because you cannot hold onto it—if they kick your hands or face and pull their foot back, you will always lose it.
If my opponent has their feet on my hips, how do I escape or defend?
Hudson Combat Academy advises not to try punching through it since there's too much pressure keeping you away. Instead, reach your hand through the back of the knee to create an escape or counter.
Where should I place my feet when I'm on my back to stay safe from a compression lock?
Hudson Combat Academy recommends putting your feet behind your opponent's knees and hiding them there, as this is the safest position for them to be in.
How do I maintain a solid back mount position before attacking with the compression lock?
Alpha BJJ emphasizes getting your feet underneath you and counterintuitively putting your weight on your feet instead of on your opponent, which allows you to take small steps back and sink your hips over theirs for a much more solid position.
