Deadlifts
Deadlifts are a classic compound bodybuilding or strength training movement which primarily targets the glutes, quads, hamstrings, and spinal erectors. Synergist muscles include the quads, hamstrings, Adductor magnus, and soleus.
In the setup phase, the lifter stands behind the bar, hinges at the hips, and grips the bar wider than shoulder-width. In the ensuing drive phase, the lifter braces his core and pushes through his heels, and attempts to lift the barbell off the ground. Finally, in the lockout phase, he stands completely erect whilst contracting the lumbar area and glutes to engage the target muscles.
