Set the pins on the power rack just below your knees and stand in front of it with a shoulder-width stance so that the bar is right up against your shins.
Bend at the knees and forward at the waist and grab onto the bar using an overhand grip just outside of your legs.
While keeping your back flat, core tight and neck neutral, lift the bar off the pins. As you pull the bar up, your knees should straighten out as you simultaneously extend your torso into an upright position.
Continue until you are standing fully upright and holding the bar out in front of your body. Lower the weight down following the same path as when you lifted it.
Rest the plates on the pins, take a deep breath and repeat.
