The hip bump sweep catches opponents when they sit too upright in your guard. By sitting up explosively and bumping your hip into them, you topple them backward. What makes it truly powerful is the chain reaction—when they base to defend, their arm becomes available for the Kimura, and if they over-commit to stopping the Kimura, the sweep opens up again. This sweep-submission chain is one of BJJ's most fundamental combinations.
Attack when they're sitting upright, not when they're driving into you. Posture up = hip bump opportunity. Driving forward = different attacks.
Explosively sit up, posting on your elbow then hand behind you. Your chest should drive into their chest.
Angle slightly to one side—you're sweeping them over your hip, not straight back. Your hip lifts under them as you post and bump.
Overhook their arm on the side you're sweeping toward. This prevents them from posting and helps with the sweep.
As they fall, keep your momentum going up and immediately establish mount. Don't stop on the ground.
Attempting when they're driving into you
The hip bump works against posture. Wait for them to sit up before attacking.
Sitting up slowly
Explosive sit-up. Slow = they adjust and base. Fast = they're falling before they react.
No arm control
Overhook or underhook on the sweeping side prevents the post that kills the sweep.
Giving up when they base
Their base hand = free Kimura. The sweep and Kimura are two halves of one attack.
