The armbar from mount is a fundamental joint lock targeting the opponent's elbow, executed from a dominant top position. It is a high-percentage submission that leverages positional control to isolate and hyperextend the arm, making it a staple in both gi and no-gi competition.

Submission
Prerequisites: Cross-face control · Establishing an underhook · Posting for base · Basic hip mobility
Steps
1
Establish a stable mount
Keep your knees wide and heels tight to their hips, with your chest heavy and head forward to maintain balance and pressure.
2
Isolate the target arm
Use a cross-face grip with one hand and your opposite hand to pin their wrist to the mat, creating a strong frame and exposing their elbow.
3
Set up the armbar grip
Slide your far-side knee up behind their head, while your near-side hand threads under their arm and grabs their wrist or triceps for control.
4
Shift your weight for base
Post your far-side hand on the mat for balance, and lean your weight forward so your hips are light and ready to pivot.
5
Swing your leg over the head
Bring your near-side leg up and over their face, placing your calf tight against the back of their head, toes pointing down to prevent escape.
6
Sit back and pinch your knees
Drop your hips to the mat, keeping your knees pinched tightly around their arm and your heels pulled in to limit their movement.
7
Secure the arm and finish
Grip their wrist with both hands (thumbs toward the ceiling), pull their arm down to your chest, and slowly bridge your hips up to hyperextend the elbow.
Key details most people miss
Keep your heels tight to their ribs and pinch your knees throughout the finish to prevent them from turning or pulling the arm free.
Your far-side knee should be close to their head before swinging your leg over, reducing space for their escape.
When swinging your leg, point your toes downward to keep their head pinned and prevent them from sitting up.
Lean forward during the transition to avoid being rolled as you step over.
Common mistakes
Failing to control the wrist allows the opponent to turn their thumb and slip the arm out before the finish.
Leaving too much space between your knee and their head gives them room to escape or stack you.
Not pinching your knees enables the opponent to rotate their body and relieve pressure on the elbow.
Leaning back too early exposes you to being rolled or having your base disrupted.
