Run, run, and run some more! You can also incorporate alot of polymetrics training that'll get your heart rate up therfore increasing your endurance! If you don't know what that is, you basically set up stations (sprints, cone drills, foot work etc.) alot of short high intensity drills! Hit em' and hit em' get that heart rate up! For a DE work on your hand skills, and foot work! You need quick hands and feet...so put some ankle weights on you wrists as well as on the ankles...then work on firing off from your stants you'll be suprised at the difference when you take those weights off! You'll build the muscle that you use for those particular things aswell as the life of those muscles(endurance) Good Luck!
Reply:Dude. Don't waste our time by asking us stuff you already know. You know that sprinting and running is the only way to do that, you're just too lazy to do it on your own so you want to hear a bunch of us tell you what to do.
Reply:Buy A NIKE SPARQ Training Parachute I Have One And I Love It, I Usually Have Ankle Weights On When I Run With It On Also. I Play Middle Line Backer And Offensive Tackle.
