Instructions

Preparation
Grasp barbell from rack or deadlift from floor with a shoulder width or slightly wider overhand or mixed grip. Stand with a shoulder width or narrower stance.

Execution
Lower bar to the top of the feet by bending hips. Bend knees slightly during the decent and keep waist straight. With knees bent still bent, lift the bar by extending at hips until standing upright. Pull shoulders back slightly if rounded. Extend knees at top if desired. Repeat.

Comments
Throughout lift keep arms and back straight. Do not lower weight beyond a mild stretch throughout hamstrings. Full range of motion will vary from person to person. Stand on an shallow platform if weight reaches floor before stretch. Those with less flexibility may have to bend knees more. Knees can be kept bent throughout movement. Also see Stiff Leg Deadlift.
