Knockout Workout - Upper body work does not always have to have pull ups and push ups nor does it require weights. A dynamic approach that employs shadow boxing moves and precise martial arts techniques pushes the muscles to work in both concentric and eccentric ways increasing effective power and speed. Don't spare yourself, the Knockout workout is here to help you.
Good advice, but there is one more. Hit that bastard hard the first time, and before he can shake it off hit him again and again. Knock him flat and kick his face in. It's not cheating or being a dirty fighter, it's called winning. Unless he's out cold never underestimate the guy. Back away after the fight is over and watch for anybody that may want to step up to the plate.
