    More Questions

    What is the primary goal of the underhook control system?

    The primary goal is to establish positional dominance by preventing your opponent from creating space or escaping. It allows you to control their hips and posture, setting up sweeps or submissions.

    How can I prevent my opponent from getting an underhook on me?

    Maintain a strong base, keep your hips low, and actively fight for wrist and elbow control. When your opponent attempts to secure an underhook, use your frames and pressure to deny them entry.

    What are some common submissions that can be set up from the underhook control system?

    From the underhook, you can effectively set up submissions like the armbar, kimura, or even a guillotine choke by manipulating your opponent's posture and creating openings.

    Common BJJ Problems & FAQ

    Q: Why do I feel like I can't breathe or my neck is getting choked when I try to get an underhook in Brazilian Jiu-Jitsu?

    This often happens when you're trying to force the underhook with your head too low, causing your opponent to drive their shoulder into your airway or neck. Instead, keep your head up and slightly angled, using your bicep and forearm to create a wedge between your chest and their torso, allowing you to breathe and maintain control.

    Q: How can I effectively secure and maintain an underhook against someone much bigger and stronger than me in BJJ?

    Against a larger opponent, focus on using your hips and base to drive forward and slightly upward, creating a scooping motion with your arm. Keep your shoulder blades tucked in and your weight low, making it difficult for them to simply push you away; your core engagement is key to generating leverage.

    Q: What is the best way to transition from an underhook to a dominant position like a side control or mount without losing the position?

    Once you have a strong underhook, use your hips to drive forward and slightly to the side, while simultaneously using your free arm to either trap their far arm or establish a collar grip. This coordinated movement shifts your weight over their center of gravity, allowing you to secure a dominant position with a clean transition.
