    Common BJJ Problems & FAQ

    Q: When I try to get the underhook in half guard, my opponent always seems to push my head down and I can't establish a good grip, what am I doing wrong biomechanically?

    You're likely not creating enough space with your hips. To achieve the underhook, actively push your hips away from your opponent's chest while simultaneously driving your shoulder into their hip socket and reaching for the underhook, creating a wedge with your forearm.

    Q: How can I effectively use my underhook in half guard to prevent my opponent from passing my guard, especially when they are much bigger than me?

    Focus on using your underhook to control their base and prevent them from stacking you. Drive your shoulder into their hip and use your legs to create a frame, keeping your hips elevated and preventing them from collapsing your guard by actively pulling them towards you.

    Q: My underhook feels weak and I can't generate any pressure to sweep from half guard, what specific body positioning should I focus on for a powerful sweep?

    To generate power for a sweep, ensure your underhook is tight, driving your shoulder deep into their hip crease, and your elbow is tucked. Then, use your free leg to hook their far leg, and simultaneously bridge your hips up and twist your torso, using your underhook as a lever to off-balance them.
