    More Questions

    What is an overhook in BJJ?

    An overhook, also commonly called a whizzer, is a position where you secure your arm over your opponent's arm and under their armpit. It's a fundamental control position used in various grappling scenarios, primarily for establishing dominance and preventing movement.

    How do I use a whizzer to stop a takedown?

    When your opponent attempts a shot, you can quickly secure an overhook on their arm and use your body weight and grip to drive down and sideways. This disrupts their balance and leverage, making it difficult for them to complete the takedown and allowing you to potentially counter.

    What are the common mistakes when using an overhook/whizzer?

    A common mistake is to only rely on the arm grip without engaging your core and hips; the whizzer is a full-body technique. Another error is to let your opponent's arm get too deep inside your own, which can lead to them breaking your grip or transitioning to a better position.

    Common BJJ Problems & FAQ

    Q: Why does my shoulder feel strained when I try to use the Overhook System (Whizzer) to control my opponent's arm?

    Shoulder strain often occurs when you're trying to muscle the whizzer by extending your elbow and rotating your shoulder externally. Instead, drive your elbow down towards your hip, creating a fulcrum with your shoulder joint and using your lats to pull your opponent's arm across your body.

    Q: How can I effectively use the Overhook System (Whizzer) to prevent my opponent from passing my guard when they are much bigger than me?

    Against a larger opponent, focus on driving your whizzer elbow deep to their hip crease, creating significant pressure and limiting their hip mobility. Simultaneously, use your other arm to control their far arm or head, preventing them from establishing strong grips and maintaining your base.

    Q: What is the correct way to transition from a failed Overhook System (Whizzer) attempt to a defensive position without getting passed?

    If your whizzer fails, immediately tuck your chin and drive your hips back to create space, preventing your opponent from collapsing onto you. While doing this, actively seek to re-establish your guard by shrimping your hips away and bringing your knees back between you and your opponent.
