For a routine, one has to use numbers, but I feel stopping because you hit a certain number is useless. You get a feel for what your capabilities are and shoot for weights that you fail when going for those sets. Sure you don't use 135 on the bench and do 100 reps because you can, but also don't use 225 for sets of 10 when you can get 15. Each set should be to failure IMO. Sure some will say this is a way to get injured and that's why you have a true and tested spotter working with you. I feel doing 4 sets of 10 really is a joke unless you are adjusting the weights each set as needed. The starting light and working heavy is a joke to me if you're keeping the same amount of reps per set. Of course you need to be properly warmed up, but you see people in the gym doing 185 for 10, then jump to 225 for 10, then 275 for 10, then 315 for 10. What the hell, if you have enough left to keep jumping like that and still get 10, then you just aren't doing what you need to be doing on the 3 previous sets to grown like you want. Those are the guys who care more about what people see them lifting and not the ones who want true results IMO.
Check this link out and you will see how I train. I change the routine up as vengeance says, but mostly the numbers of reps after 8 weeks or around there. I tend to do most of the same lifts, but throw in some different shit here and there and even change the order in which I do each exercise in the routine. Different strokes for different folks as they say, some are stuck in their ways and won't ever change, but those are usually the guys in the gym who look the same year after year. You know the guys I'm talking about. LOL!
