Exercise Advice: Using the Smith Machine, grab the barbell with both hands using an overhand grip about shoulder width apart and let the barbell hang down in front of your body. Begin this movement by bending at the waist and lowering the barbell to the floor. Be sure to keep your legs as straight as possible (a slight bend is ok) and really let the weight of the barbell bring you down. On the way up, really focus on your butt and hamstrings to pull the weight back up. It is very important to keep your back straight and rigid throughout this exercise and to let your legs and butt do the work.
