Deadlifts target the entire body. They stimulate growth all over. They're a true man's exercise (and a woman's, should they decide to lift). They test your will and raw strength. They're great to strengthen your lower back, but biceps, the entire back complex, hamstrings, glutes, quads, calves, forearms, neck, abs, the core in its entirety. Everything is hit by these. Learn proper form with lower weight. You will learn to love to hate to deadlift...or something. Just do it man.
