A third exercise that is great for hamstrings is a special deadlift we do for squatting. It took Matt Dimel from 820, where he was stuck for 18 months, to a 1010 squat. Use a shoulder width stance and grip the bar at the rings. First, stand up with an arched back. Then squat down with the glutes pushed far to the rear, never letting your knees move forward. Lower the bar to just below the knee very fast. Then with a strong concentric action return to the starting position. These partial deadlifts are done in a very, quick manner, first dropping the bar from an erect position to just below the knees, then catching the weight and lifting it explosively. Two sets of 20 reps can be done 4 times a week for 2 weeks with 30-40% of your 1 rep max. Then switch to a different exercise.
