This probably sounds like a dumb question, but how do you guys go about gaining strength on a typical bodybuilding split routines? For example, I consider a typical chest workout to look something like:
Incline Barbell Bench: 4 x 6-12
Flat DB Bench: 4 x 8-12
Incline DB Flyes: 4 x 10-15 or whatever
When you first start lifting you could probably add weight and/or reps every workout, but I don't see how once you reach an intermediate level of strength you could expect to make linear strength gains like this. Most strength oriented routines usually have you working at a different percentage of your 1RM each week so you can continue to make strength gains without trying to add weight or reps every single time you do that exercise.
How do you guys go about continuing to get stronger once you've reached an intermediate or advanced level or strength when doing bodybuilding routines? Do you just keep hammering away at the same exercises and hoping that you'll eventually get stronger, or do you rotate different exercises (for example flat barbell bench to flat dumbbell bench) or do you change rep ranges?
