Stiff Leg Deadlifts Ildi tried to teach me the proper form of Stiff Leg Deadlifts for weeks. I was having some low back pain at the time. That interfered with my technique. Now that my back is limber I've got the hang of it. I love doing them now. Yesterday I used a 50 pound bar bell. It was very hard for me to carry the barbell to the corner. My hamstrings are very sore today which is a good sign. I'm looking forward to more Stiff Leg Deadlifts next week.
