Armbar

From Knee-on-Belly to an Elbow Joint Lock

Key Steps

• Step 1: Establish control and isolate the arm

  From knee-on-belly, anchor your near arm around the opponent's wrist to pin their elbow to your chest. Keep the head high, eyes forward, and base stable.

• Step 2: Create the angle and prepare the lever

  Slightly shift your hips to the side and turn your torso perpendicular to the attacked arm to open space.

• Step 3: Swing the leg over and secure the position

  Slide your far leg over their head and behind their arm, pinning the arm between your thighs and trapping the wrist.

• Step 4: Finish with hip extension

  Drive your hips forward while maintaining the wrist control to hyperextend the elbow; hold until the referee or opponent taps.

Application

• Gi and No-Gi: In Gi, grip the wrist with your top hand and use the lapel or belt as secondary control; in No-Gi, rely on wrist control and torso pressure. This is a versatile submission from knee-on-belly and is a staple in many jiu jitsu moves and bjj techniques.
• Not beginner-friendly: It requires hip control and precise arm isolation; with coaching, beginners can learn gradually.

Mistakes

• Letting the elbow flare or losing control of the wrist
• Over-rotating hips without securing the arm
• Not maintaining a stable base; the opponent can stack or roll

Tips

• Keep your knee on the body while you work; breathe steadily; practice the step-by-step with a cooperative partner; avoid forcing the finish.
