Just a question I've been wondering about for the past few months. I've been reading through Arnold's encyclopedia of bodybuilding and came across a section where he talks about varying ways to add resistance to your workouts so that your body doesn't become adapted to the training, and then still has reasons to grow. Some of them include Supersets, Drop Sets, Tri Sets etc.
I've always trained from the start in a way that lets me see progress which I write down in a journal. I do this by adding weight. I've always added weight as a form of resistance. Now the problem I have is, when exactly should I be adding different types of resistance to "shock" my muscles, so they don't become adapted to the training? Let's say I was to add supersets to my Chest day... That's all well & good, but then my strength will eventually stop progressing because I'm jumping from one exercise to another with no rest in between. If I did Barbell Flat Bench followed by Incline Dumbbell Bench in a superset then I don't know if my Incline Dumbbell Bench weight would increase in the future due to it coming straight after the previous exercise, with no rest in between. And even if it did increase, it wouldn't be the true amount I could lift, it'd just be the amount I could lift after doing an exercise right before it with no rest in between. So the progression would seem weird, if there was even any at all.
I'm just not sure how and when to add different types of resistance such as supersets etc, because it detracts from my main form of progression which is adding weight to the exercises. Which is the better form of progression from a bodybuilding point of view, because I've always read that you should be aiming to add weight to your exercises all the time, even if by just 1-2lbs? I just don't know.
Would really appreciate some help with this.
