Ben, if you really get into this, his recent DVD/Book combo is good, too.
RossTraining - Full Throttle Conditioning
Read the review over at Tony's. It's a good product, as long as you know it's for you. $25. I'd buy it again, just for the book. It's all about simplicity. It's got a brief section on tapering, which is why I thought of it here.
Oh, TRX vs Elite rings? Having tried them at JP's, I like them, too. The TRX is more flexible for outside work and attaching to trees and doorways of hotels, but those rings were pretty sweet. Ring dips were sure fun at the Summit, plus watching Chris do the Muscle-Up was cool. He strong. I couldn't do even one.
