How do I defend against takedowns in BJJ?

Effective takedown defense has multiple layers. The first layer is distance management, keeping your opponent at a range where they cannot easily shoot. The second layer is grip fighting, denying them the grips they need to initiate takedowns. The third layer is the physical defense when they close the distance. Against single and double leg shots, the sprawl is essential. Drive your hips to the ground while posting on their back, which stuffs the takedown and can lead to front headlock attacks. Against clinch-based takedowns from judo, controlling the inside position with underhooks and keeping your hips back prevents throws. In BJJ, you always have the option to pull guard, which is both a technique and a defensive strategy. If someone catches your leg, sitting to guard rather than hopping on one foot is often the smartest choice. Practice takedown defense regularly because it is a perishable skill that deteriorates without maintenance.
