One of the nice things about 5/3/1 is it's easy to gauge your progress from cycle to cycle. If you get in there and rep out your last set (aka "money set") each week, you can see your strength going up from week to week and month to month. I ran 5/3/1 as written for 8 cycles and loved it. I'm still doing my upper body in 5/3/1 style. Have fun and don't be afraid to change your assistance exercises up if you feel that they're not working for you.
