Mount Armbar Position Drill

The mount armbar position drill practices moving from mount into arm control with a cooperative partner, without finishing the submission. It develops positioning, coordination, and controlled transitions.

Higher injury risk. Read the safety notes before adding weight.

How to do it

  1. Kneel astride your partner's torso in a light mount while they offer one bent arm.
  2. Support the offered arm with one hand at the wrist and the other above the elbow.
  3. Slide the knee on the controlled-arm side beside your partner's ear.
  4. Rotate your hips toward that shoulder with your opposite thigh across your partner's upper torso.
  5. Bring the leg nearest their head over their face to the far side.
  6. Sit beside their shoulder with the controlled arm between your thighs, keeping their elbow comfortably bent.
  7. Move your legs clear of your partner while supporting their arm.
  8. Release their arm to end the repetition.

Form cues

  • Keep your weight light.
  • Leave your partner room to breathe.
  • Use only a gentle grip.

Common mistakes

  • Falling backward into positionKeep your torso upright over your hips as you settle into the seated position.
  • Twisting the wristAllow the wrist to follow the arm's natural alignment rather than forcing the thumb into position.
  • Clipping the face with your footLift your foot high enough to clear your partner's face during the leg transition.

Safety

A sudden drop or pull can straighten the trapped arm and injure the elbow before your partner can react. Forced rotation can also strain the shoulder.

  • Learn the transition under qualified grappling supervision.
  • Use a cooperative partner without resistance, at a pace that lets either person stop anywhere.
  • Agree on a tap and verbal stop signal; release pressure immediately at either signal or any discomfort.
  • Apply no submission pressure or upward hip drive.

Use a grappling dummy if either partner has elbow, shoulder, or neck pain, and seek advice from a physiotherapist before returning to partner practice.
