Also known as: Hook Sweep, Elevator Sweep
The butterfly sweep uses your hook (foot inside their thigh) to elevate and turn your opponent over while your upper body grip prevents them from posting. It's one of the most versatile sweeps in BJJ—working against standing, kneeling, and larger opponents. The key is understanding that you don't lift them with strength; you fall to the side while your hook redirects their weight.
Your hook doesn't lift—it redirects. Fall to the side and let your hook guide their weight where their base isn't.
Underhook on the sweeping side controls their shoulder. Without it, they post and stop the sweep.
Your head should go toward their armpit on the sweeping side—head leads the body.
Fall to your side while your hook elevates. Don't try to lift them straight up.
Follow your momentum and come up to top position. Don't pause after the elevation.
Trying to muscle them over
Use timing and angle, not strength. Fall to the side as you hook elevate.
No underhook
You need upper body control. Underhook prevents their post.
Wrong angle
Angle your body 45 degrees. Straight-on sweeps are easily stuffed.
Not following through
Commit to the sweep and come to top immediately. Hesitation = scramble.
