Lee I'm glad to see you using the 5x5 it truly is a great routine. It's tough to start because it doesn't seem like your really working very hard but as you progress and the poundages increase, you really start to notice it. I know some people on here debate about whether soreness is a sign of anything but I feel that you do need to get good and sore to stimulate real growth, but you must give time to rest and recover in order to take advantage of that soreness. My buddy tried the 5x5 on chest day a week ago and thought it was gay until the next three days that he was sore as hell. I do chest on Monday and by Thursday my chest is starting to return to normal. My chest gets sore late at night the day I do chest, it's incredible. I do 5x5 straight bar curls for bi's as well and that is unbelievable for size and strength. I was scepticle about using 5x5 for bi's at first but it's amazing. Since Feb 1st, my arms have gone from 16.25 to 16.75, it's amazing. My arm workouts don't even seem that tough when I do them but the next three days prove the work did some good.
