2 Part Lesson — Marcelo shoves his opponent to rebuild momentum: [I] If your opponent tries to drive you flat while kneeling against your Seated Butterfly Guard, angle your torso forward and crash into his upper body with Over/Under Control; this may happen quickly so you have to train yourself diligently to prepare for the crunch. Once stalled out, push his elbow in toward center and flip the opponent off his base with Hook Sweep. [II] If you both crash forward with your elbows protecting against hooks, quickly pop your opponent's shoulders away from your chest and time his reentry with a quick and deep Hook Sweep from Butterfly.
