Stand in front of an Olympic barbell and take a stance just narrower than shoulder width with your toes pointed directly forwars. Bend your knees and drive your hips back but don't allow them to go lower than your knees. Brace your core, keep your chest up and keep a neutral spine as you take a firm grip of the barbell. Choose either an overhand or mixed grip depending on your preference. Hands should be slightly wider than shoulder width placed just outside of your legs. Shoulders should stay back and traps should stay relaxed, with your arms fully extended gripping the barbell. This is the start position. Imagine then pushing the ground away from you with your feet and as you do so driving your hips forward and extending at the knees. To keep your spine neutral and shoulders back also imagine that you are squeezing oranges into your armpits as you pull the bar from the floor. All the while exhaling as you do so. Pause at the top when you've reach full hip extension and are standing tall. Then return to the start position with control, by bending your knees and driving your hips back , inhaling as you do so.
