Deadlifts especially work the adductor muscles of the hips. Torso muscles such as the rectus and transverse abdominus â commonly known as abs -- and the outer-torso serratus anterior and obliques get a secondary workout as the lifter keeps them tight and engaged throughout the motion of the exercise.
Full length barbell deadlift style won't work because knees get in the way when the rump gets down by the floor. In dead lift the rump is high and the shins vertical so the bar clears. Not so with squats, thus the dumbbell solution for safety. The loss is the need to develop balance when the weight is over your neck.
