Bicep Slicer

SAFETY: Bicep Slicer targets the Bicep muscle and elbow joint. Risk: Bicep muscle tear or severe contusion. Release immediately upon tap.

Position Variants

From Position	Success Rate	Top Injury Risk	Key Difference
Crucifix	52%	Bicep muscle tear or severe contusion

The Bicep Slicer is a devastating compression lock that applies crushing pressure to the bicep muscle and hyperextends the elbow joint. This advanced submission works by trapping the opponent’s arm between your shin and forearm, creating a lever that compresses the bicep against the humerus bone while simultaneously hyperextending the elbow. Most commonly applied from the crucifix, truck, or modified mount positions, the bicep slicer is a technical submission that requires precise positioning and control. The compression creates intense pain in the bicep muscle belly, while the hyperextension threatens the elbow joint, creating a two-fold attack that is difficult to defend. This submission is particularly effective in no-gi grappling where the opponent cannot use gi grips to defend, and it serves as an excellent backup when traditional chokes or arm locks are unavailable. The bicep slicer’s effectiveness comes from its ability to attack an area that most grapplers do not regularly condition or defend, making it a high-percentage finish when the proper positioning is achieved. Understanding the mechanical advantage required and the precise angles needed separates successful application from ineffective attempts.

Safety Guide

Injury Risks:

Injury	Severity	Recovery Time
Bicep muscle tear or severe contusion	High	3-6 weeks for muscle damage, up to 12 weeks for severe tears
Elbow hyperextension or ligament damage	High	4-8 weeks for moderate sprains, 3-6 months for severe ligament tears
Radial nerve compression	Medium	1-3 weeks for temporary nerve irritation

Application Speed: EXTREMELY SLOW - 5-7 seconds minimum with constant communication

Tap Signals:

• Verbal tap or verbal distress signal
• Physical hand tap on opponent or mat
• Physical foot tap on mat
• Any vocalization of pain or distress
• Frantic body movement indicating distress

Release Protocol:

1. Immediately release all pressure on the bicep/elbow
2. Remove the shin from behind the opponent’s elbow
3. Release any grip controlling the wrist
4. Allow the opponent to straighten their arm naturally
5. Check with partner about their condition before continuing

Training Restrictions:

• Never apply sudden or explosive pressure
• Never use full competition speed in training
• Always maintain verbal communication during application
• Never practice on beginners until they understand tap urgency
• Do not apply this submission if opponent has existing elbow or bicep injuries
• Always ensure training partner has clear tap access with free hand

Variation Details

Bicep Slicer from Crucifix: The most common and highest percentage application. From the crucifix position, you have both arms controlled, making it easier to isolate one arm for the bicep slicer. Use your leg positioning to trap their arm while your hands control their wrist, creating the perfect angle for compression. (When to use: When you have established crucifix control and the opponent is defending chokes by tucking their chin or protecting their neck. The bicep slicer becomes an excellent alternative finish.)

Bicep Slicer from Truck: From the truck position (twister control), you can attack the near-side arm with a bicep slicer. This variation often surprises opponents who are focused on defending the twister or back take. The leg configuration in the truck provides natural leverage for the shin placement behind the elbow. (When to use: When attacking from the truck position and the opponent successfully defends the twister by straightening their body. The bicep slicer becomes available on the arm closest to your legs.)

Modified Mount Bicep Slicer: From a modified or technical mount where you have one arm trapped under your leg, you can transition to a bicep slicer by threading your shin behind their elbow while controlling their wrist. This requires precise positioning and is typically a transition from failed mount attacks. (When to use: When mounted and the opponent is defending by keeping their arms tight to their body. If you can isolate one arm and trap it under your leg, the bicep slicer becomes an effective attacking option.)

North-South Bicep Slicer: A less common but effective variation from north-south position. Isolate one arm and use your leg to create the fulcrum behind their elbow while controlling the wrist with your hands. This requires significant flexibility and control but can catch opponents off-guard. (When to use: When transitioning through north-south and the opponent extends an arm defensively. The unusual angle can make this variation particularly difficult to defend.)
