Worked with Brandon doing basic movement drills. He'd move and present a target, I'd have to move into range and jab. After doing this a while, expanded it into a jab/cross combo, which made it pretty obvious when my footwork wasn't right. If I let my rear foot trail too far, it steals range and power from my cross. Move first, then hit.
Coach also gave me some tips on my stance
* Chin down
* Knees bent
* Stay on balls of feet
