My flexibility sucks. I've been stretching for the past week several times a day. I want to increase my flexibility and I already know about the benefits stretching has in regards to growth. I'm going to start doing dead lifts soon. I wanted to practice the movement with a little bit of weight, hence the rack pulls. I'll definitely be going light when I start them...although not too light. I think I will start doing them along with rack pulls on that same day..and then slowly phase out rack pulls while increasing dead lifts. I agree, it's not a replacement. Squats have strengthened my lower back a LOT. Right now, I think it's not a matter of weight, it's more about the lower back strength, so I might as well start this week with low weight.
