    Why Mount is Perfect for Submissions

    The mount position gives you unmatched control over your opponent's body. You can isolate their arms, control their head and neck, and apply pressure to their entire torso. This makes submissions from mount highly reliable and devastating.

    Armbar from Mount

    One of the highest-percentage submissions from mount:

    • Control your opponent's arm by trapping it across your body
    • Post your foot on the ground for leverage
    • Pivot your hips and extend the elbow over your hip
    • Apply steady pressure until they tap or the arm locks
    2

    Rear-Naked Choke (RNC) from Mount

    Transition to RNC when opponent's arms are too active:

    • Position your hands behind their neck in a collar grip
    • Lock your hands by grasping your wrist or interlocking fingers
    • Sink your weight and apply steady pressure to the neck
    • Control their hips to prevent escape
    3

    Triangle Choke from Mount

    Setup from mount by isolating an arm:

    • Trap one arm against their body with your knee
    • Thread your other leg over their shoulder
    • Lock your legs in triangle formation
    • Adjust your hips and squeeze for the tap
    πŸ’‘ Pro Tip: The key to mount submissions is patience. Don't rush the finish. Control your opponent's movement first, then methodically set up the submission when they're exhausted and panicked.

    Americana and Keylock from Mount

    These shoulder submissions are highly effective from mount. The americana isolates the arm and shoulder joint, while the keylock works by locking the arm against their own body.

    Chestband Choke

    An advanced submission where you use your lapel to choke from the front mount position.

    Common Mistakes in Mount Submissions

    Sitting Too High

    Mounting high on the chest gives your partner room to bridge and roll. Sit low β€” hips near the belt line β€” and sprawl your weight through your knees.

    Reaching Forward Too Early

    Leaning forward to grab the collar before establishing hooks invites the upa escape. Secure weight distribution before attacking.

    Neglecting Hip Control

    Without controlling the hips through knee pressure and foot hooks, escapes become trivially easy. Drive knees inward and maintain active pressure.

    Abandoning Base

    Losing base while attacking submissions allows reversals. Keep your base wide, weight centered, and never over-commit to a single attack.

    More Questions

    How do I prevent my opponent from bridging out of mount when I'm setting up an armbar?

    Control your opponent's hips by keeping your knees tight to their sides and your weight low. A strong cross-face can also help limit their ability to generate upward momentum for a bridge.

    What's the best way to transition from mount to a Rear Naked Choke if they defend the armbar?

    If they tuck their arm to defend the armbar, use that opportunity to drive your shoulder into their face and transition to their back. Secure your seatbelt grip and begin working for the choke.

    My opponent keeps escaping mount by turning away. How can I counter this?

    When they turn away, immediately switch your hips and try to secure a "grapevine" with your legs to control their hips. This will prevent them from creating space and turning fully to escape.

    Common BJJ Problems & FAQ

    Q: When I try to do the armbar from mount, why does my opponent's arm feel like it's not extending enough and I can't finish the submission?

    To effectively finish the armbar from mount, you need to isolate the opponent's arm by controlling their bicep with your opposite side hip and using your leg to hug their head, preventing them from posturing up or turning in. Ensure your hips are driving *down* into their chest, creating a strong fulcrum point, and your free leg is extending their arm by creating leverage on their elbow joint.

    Q: How can I maintain my mount position securely when my opponent is trying to buck or shrimp away, especially if they are much larger than me?

    To maintain mount against a larger opponent, focus on keeping your weight low and forward by driving your hips into their chest, almost as if you're trying to sit on their sternum. Use your knees to grip their hips and inner thighs, creating a tight base, and actively use your chest to pressure their shoulders, preventing them from creating space to buck or shrimp.

    Q: When I attempt a Rear Naked Choke (RNC) from mount, my opponent keeps turning their chin into my arm, and I can't get the choke to sink in. What am I doing wrong biomechanically?

    To secure the RNC from mount, you must first break their posture by driving your chest into their upper back and controlling their head with your armpit. When applying the choke, ensure your choking arm's bicep is firmly against their carotid artery, and your non-choking arm is wrapped around their head, with your forearm pressing on the back of their skull, creating a vice-like grip that prevents them from tucking their chin.
