The deadlift is one of the best all-in-one exercises because it develops power in your thighs, buttocks, hips, forearms, and yes, your back. Be advised, however, if you rely too heavily upon the back -- failing to squat and lift with your back perpendicular to the ground -- you are at a high risk for injury. In short, you're doing the deadlift wrong. Let's look at how to do it correctly.
Put the weight you will lift on a straight bar, remembering to be conservative in the early going. Stand with feet shoulder-width apart, bend at the hips and knees while looking up to insure your back remains straight. Grab the bar slightly wider than shoulder width with one palm facing out and the other palm facing in for stability. Lift the bar using your legs and torso until you're standing up straight. At the top of the lift, pull your shoulders back. Pause momentarily before squatting back down and placing the bar on the floor [source: Iron Workout]. Repeat approximately 10 times. With practice, you'll be able to increase the weight and the number of sets.
As you can see, the tools for getting a ripped back are readily available and, in some cases, involve nothing more than your own body weight and a small space to work in. All you need is the desire and discipline to stick with it.
