SAFETY: Reverse Armbar from Mount targets the Elbow joint (hyperextension with reverse rotation). Risk: Elbow hyperextension with lateral stress. Release immediately upon tap.
The Reverse Armbar is an advanced elbow hyperextension technique distinguished by its inverted body positioning relative to the standard armbar. Unlike the traditional armbar where you face toward your opponent’s head, the reverse armbar requires you to rotate your body 180 degrees so your hips face toward their feet while maintaining control of their arm. This submission is particularly effective in scramble situations, failed standard armbar attempts, or when opponents defend the conventional armbar by turning their thumb down. The reverse mechanics create unexpected leverage angles that catch even experienced practitioners off-guard, as defensive instincts trained for standard armbars often fail against this variation. The technique demands precise hip positioning, tight arm isolation, and careful rotational control to prevent escape while maintaining submission pressure. Success hinges on understanding how the reversed body angle changes the leverage dynamics—your legs must control their shoulder and head differently, and your hip placement becomes critical for generating breaking force without losing control.

Key Attacking Principles
What are the key principles for executing Reverse Armbar from Mount?
- Hip rotation must precede extension to establish proper angle
- Arm isolation requires thumb-up positioning before rotation begins
- Head and shoulder control prevents rolling escapes during transition
- Your hips must stay high and tight to the arm throughout
- Rotational momentum must be controlled to maintain arm security
- Extension pressure comes from hip elevation, not pulling with hands
- Body weight distribution shifts toward opponent’s feet during finish
Prerequisites
What do you need before attempting Reverse Armbar from Mount?
- Secure two-on-one arm control with opponent’s arm fully extended
- Opponent’s thumb must be pointing up (supinated position)
- Clear space to rotate your body 180 degrees without obstruction
- Head and shoulder control established with your legs
- Hip positioning must be tight to their arm before rotation
- Balance maintained throughout rotational transition
- Opponent’s defensive frames must be cleared or controlled
Execution Steps
How do you execute Reverse Armbar from Mount step by step?
- Establish Standard Armbar Control: From mount or guard, secure traditional armbar position with both hands gripping opponent’s wrist and forearm. Ensure their arm is fully extended with thumb pointing upward. Your legs should control their head and far shoulder, with your near leg across their chest or face. This standard position serves as the foundation for the reversal. (Timing: 2-3 seconds to secure)
- Pin Arm to Your Chest: Pull opponent’s arm tightly across your chest, pinning their tricep against your sternum with both hands maintaining wrist control. This pin is critical—any space between their arm and your body will allow escape during rotation. Your elbows should be tight to your sides, creating an unbreakable connection. Keep their elbow slightly bent to prevent them from pulling out. (Timing: 1-2 seconds)
- Initiate Hip Rotation: Begin rotating your entire body 180 degrees toward opponent’s feet while maintaining the arm pin to your chest. This rotation must be smooth and controlled—jerky movement will lose arm control. Your head should track toward their feet as your hips rotate over their arm. Keep your knees tight together during this phase to prevent their arm from slipping between your legs. The rotation happens around the axis of their trapped arm. (Timing: 2-3 seconds controlled rotation)
- Reestablish Leg Control in Reverse: As you complete the 180-degree rotation, reposition your legs so your near leg crosses their head/neck area and your far leg pins their near shoulder. Your body is now inverted—your hips face their feet while controlling their arm. Squeeze your knees together to trap their arm between your thighs. Their arm should be deeply isolated with their elbow pointing upward and their wrist still secured at your chest. (Timing: 2-3 seconds to stabilize)
- Adjust Hip Positioning for Breaking Angle: Elevate your hips slightly and ensure their elbow is positioned just below your pubic bone. The breaking point of the elbow must align with your hip fulcrum for maximum leverage. Your lower back should be slightly arched, and your grip should shift to their wrist with thumbs on top. This position creates the mechanical advantage—their arm is isolated with no escape route, and your hip position generates all the breaking force. (Timing: 1-2 seconds)
- Apply Controlled Extension: Slowly elevate your hips upward while pulling their wrist toward your chest with both hands. The extension must be gradual and progressive—this is where injuries occur if rushed. Focus on hip elevation rather than wrist pulling. Maintain constant communication with your partner. Stop immediately at any tap signal. The submission pressure comes from your hips pressing down on their elbow while their wrist is pulled in the opposite direction, creating hyperextension in the reverse plane. (Timing: 3-5 seconds progressive pressure)

Opponent Defenses
How might your opponent defend against Reverse Armbar from Mount?
- Rolling toward you during rotation phase (Effectiveness: High) - Your Response: Widen your base with legs spread, pin their head more aggressively with your leg, and accelerate through the rotation before they can build momentum. If they succeed in rolling, follow through to mount or side control. → Leads to Mount
- Grabbing their own gi/body to create defensive frame (Effectiveness: Medium) - Your Response: Break the grip immediately by pulling their arm deeper across your chest before rotating. Use your leg pressure on their head to disrupt their grip attempt. Once rotation begins, their ability to grip decreases significantly. → Leads to Mount
- Pulling elbow back to create bend during rotation (Effectiveness: High) - Your Response: Keep the arm pinned extremely tight to your chest throughout the entire rotation. If they create any bend, pause the rotation and re-extend the arm fully before continuing. Never attempt to finish with a bent arm. → Leads to Mount
- Stacking pressure by driving forward during setup (Effectiveness: Medium) - Your Response: Use their forward pressure to facilitate your rotation by timing the reversal as they press. Their momentum helps your rotation. Alternatively, abandon the reverse armbar and transition to triangle or omoplata. → Leads to Closed Guard
