Basic Shadowboxing

what are some basic shadowboxing drills?

what are some of the things I should look out for: elbows flaring out, chin tucked, shoulder to chin on punch, hands up,....what else?

anyone?

speed, relax, footwork, fakes (hand movements, foot movements, body movements, telegraphing fake targets) angleing off your punches, angleing off their punches, hands up, head movement, combos, no leaning

www.shadowboxing.com has a good video out by Jim Hoover. I also like Bas' MMA workout, I usually use the Bas tape but throw the sidewinder punches.
