Sorry it's been so long everyone! Here's a great drill I use for teaching lateral movement. Give this a try. You get a lot of good work here working on the shuffle. Stay low and get a good push off the back leg. Make sure you stick the landing and don't make it sloppy. If it looks right, chance are you're doing it right with this exercise. Very self explanatory but can really help you improve multiple aspects of movement.
ps. sorry its so small we held the camera the wrong way..... click on the youtube link to see it a little better. but you'll get the point and i'll get better at make videos
