Adding weight is fine, until you get to a place where you can only do 5x5. The Brooks Kubik version of 5x5 is pretty good. Something like:
Day 1 - Bench - 1WU, then: 5,4,3,2,1 (5) - Bicep Curls - 5x5 - Bent rows - 5x5 - Tricep Pushdown - 5x5 - Crunches
Day 2 - Squat - 5x5 - DB Press - 5x5 - Incline Db Curls - 5x5 - Close Grip Bench - 5x5 - Crunches
Day 3 - Deadlift - 1WU, then 5,4,3,2,1 - Bench - 1WU, 5x5 - Pull Downs - 5x5 - DB Press - 5x5 - Crunches
Day 4 - Neck - 5x5 (or) Shrugs - 5x5 - JM Press - 5x5 - Forearms - 5x5 - Calf Raise - 4x10 - Crunches
