i've read through 0311's post on DFT 5x5 a few times now and i have a few questions about that method of training that are still unclear to me. and if anything i ask here is answered in another post or somewhere in the DFT 5x5 guide, please let me know so i can look it over. first off in all of the suggested workouts, squats are always listed, but those are the bane of my existence (i'm 6'5" and from what i've heard, all other tall guys hate squats; particularly always seems to hurt my back). so is there any suitable substitute? also for the sets/reps do you start at a certain percentage of 1RM and then move up incrementally or just take one weight and stay with that for 5 sets?
