I was reading the other post about deadlift lockout strength and they suggested using bands. Right now its easy for me to get the bar off the ground but it slows down a lot right above the knees. I've been doing rack pulls and heavy upper back exercises but I want to incorporate band work for my heavy sets. What type of bands should I be getting if I want to pull like 455 off the ground but have the lockout over 500 lbs? Can the tension be varied with the same set of bands?
