3) Straight leg deadlifts

This exercise aims for the hamstrings and the lower back.
The subject stands straight up, legs locked, barbell in hands, with a shoulder-width overhand grip. He/she then slowly leans forward keeping the legs locked and the back straight, until his/her torso is about parallel to the floor. Then he/she - using the spinal erectors and the hamstrings straightens back up to the starting position.
Extra consideration:
- you might want to do this exercise standing on a bench so that you get the max possible range of motion.
- by its nature this exercise requires less weight than the regular deadlifts.
