What is the Omoplata?
The omoplata traps an arm with your legs and rotates the shoulder by sitting up and driving forward. It completes the classic guard submission triangle — triangle choke, armbar, and omoplata — giving bottom players multiple finish lines from the same grip setup.
Setup
- From triangle setup, thread the trapped arm across your body instead of locking the neck.
- Sit up, place the leg over the shoulder, and control the hips with your free leg.
- Grip the waist or belt to prevent them from jumping over your legs.
Execution
- Pinch knees and sit perpendicular to the opponent.
- Drive forward with chest and hips while lifting the trapped elbow.
- Roll through if they posture up, following into a finish or sweep.
Finishing
- Keep their posture broken — posture kills omoplata pressure.
- Use the lock as a sweep when they base wide; come up on top into side control.
⚠️
Safety Note
Omoplata loads the shoulder joint. Finish with controlled hip drive in training and avoid explosive twists when their posture is already broken.
Primary Targets
- Shoulder
Key Concepts
- Same entry as triangle — change the finish based on arm position.
- Sit-up momentum matters more than leg strength.
- Treat omoplata as a positional sweep when the submission stalls.
Primary Entries
- Failed triangle when the opponent hides their neck but leaves an arm across.
- Collar-sleeve guard when they post a hand on the mat.
- Spider or lasso guard when one arm extends.
Defenses & Counters
- Expect posture and base that stall the sit-up — break posture or roll through before forcing the lock.
- Watch for jump-overs that clear your legs; grip the waist/belt and follow the shoulder line.
- If they stack hard, convert to sweep or return to triangle/armbar rather than ripping the shoulder.
Follow-Ups
- Triangle when they pull the arm back inside the hip line.
- Armbar if they stack forward and straighten the trapped arm.
- Sweep to side control or back take on the roll-through.
- Triangle when they pull the arm back inside.
- Armbar when they stack forward.
Training Drills
- Triangle-omoplata-armbar flow rounds from closed guard.
- Sit-up omoplata entries with hip angle emphasis.
- Roll-through sweep to top control repetitions.

Summary
The omoplata completes the guard submission toolkit. Learn it as part of a chain — when the triangle closes the neck or the armbar straightens the arm, the omoplata attacks everything in between.
