Rather than a normal bob and weave, go down into a full crouch. From there, explode upwards into an uppercut. A follow-through jump is optional.
"I don't want them to like me, because when I'm in the ring, punches fly to the face. It is not a tenderness time. I am not falling in love. And he knows that when the fight starts I am kicking faces."
- Wanderlei Silva
