Stand with your feet shoulder width apart or slightly closer. Step to the bar so that your feet are under it, bend your knees to about 90 degrees, flatten your back, and grasp the bar with a shoulder width or slightly wider overhand grip. 
Straighten your legs and then your back to lift the weight. Keep the bar close to your body. Pull your shoulders back slightly in the top position. Keep your arms straight throughout the exercise.
Slowly return to the starting position.
