Can anyone explain how to do the Spider Web drill that Sergio Martinez does as an alternative to sparring? The drill I'm talking about can be found at 9:20 in "Chavez Jr. vs. Martinez: 24/7 - Full Episode #2" (if you google whats in the quotation marks you will be able to find a youtube link to it. I can't post it cause I don't have enough posts). Or does anyone know of any other drills that let you simulate a fight outside of just regular shadowboxing? And quite importantly can anyone recommend any footwork drills other then shadow boxing and the mimic drill? Thank you guys!
