Armbar

Quick Introduction​

The armbar is the most universal submission in BJJ, hyperextending the elbow joint using your hips as the lever. Available from virtually every position — mount, guard, side control, back, and transitions.

Position Overview​

From: Mount (primary), Closed Guard, Side Control | Finish: Hip extension against elbow joint

From Mount (Classic)​

  1. Achieve high mount with knees in their armpits
  2. Control one arm across your chest (wrist-to-shoulder)
  3. Post opposite hand on mat, swing same-side leg over their head
  4. Fall to your hip toward their head — keep chest connection until the last moment
  5. Second leg crosses their body for stability
  6. Pinch knees together around their shoulder
  7. Both hands grip wrist (thumbs pointing up), pull toward your chest
  8. Lift hips smoothly for the finish

Key detail: Fall toward their head, not away from their body. Falling away lets them come up on top.

From Guard​

  1. Control their posting/reaching arm at the wrist
  2. Hip escape 30-45° to the side (away from controlled arm)
  3. Opposite hand controls tricep or gi at elbow
  4. Throw leg over their head, other leg cuts across their back
  5. Pull them into you while falling back; pinch knees
  6. Thumbs-up wrist grip, lift hips to finish

Key detail: The hip escape angle is what makes the leg-over-head possible. Skip the angle, miss the armbar.

From Triangle (Combination)​

  1. Triangle locked or partially set up; they defend by posturing
  2. Their arm is already isolated by your legs
  3. Release triangle, capture arm with both hands
  4. Swing legs to armbar position (one over head, one across body)
  5. Finish hip extension — can return to triangle if defended

Core Principles​

  1. Control the wrist — lose the wrist, lose the submission
  2. Hips, not arms — your entire body versus their one elbow
  3. Pinch knees — any gap allows the arm to escape
  4. Thumbs up — supinated grip is stronger and prevents rotation escape
  5. Slow, controlled pressure — joints don't heal; feel for the tap

Common Mistakes​

MistakeFix
Thumb-down (pronated) gripThumbs up — stronger leverage, prevents rotation
Knees apartPinch tight around their shoulder throughout
Hips too lowHips above their elbow for maximum leverage
Falling away from headFall toward their head; away = they escape on top
Cranking fastSlow pressure — serious injury risk in training

Next Steps​

  1. Triangle - Perfect combination; armbar defense creates triangle
  2. Kimura - Alternative arm attack when they roll to defend
  3. Hip Bump Sweep - Creates the armbar opening from guard
