In a squat rack or cage, grasp the bar as far apart as is comfortable and step under it. Place it on your lower traps, squeeze your shoulder blades together, push your elbows up and nudge the bar out of the rack. Take a step or two back and stand with your feet at shoulder width and your toes turned slightly out. Take a deep breath and bend your hips back, then bend your knees to lower your body as far as you can without losing the arch in your lower back. Push your knees out as you descend. Drive vertically with your hips to come back up, continuing to push your knees out.
