Exercise Advice: Stand in an area just in front of a squat rack. Grab a barbell with both hands using an overhand grip and hold the barbell behind you, just below your butt. Begin this exercise by squatting as though you are going to sit down in a chair. Squat to a point to where your thighs become parallel to the floor and then return to the start position. It is very important that you keep your back as straight as possible throughout this movement (one way to help do this is to focus your eyes on a spot high on the wall in front of you throughout the entire exercise).
