Really? You don't think supersetting within a muscle (St. BB Curls and Std. Incline curls for example) can exhaust more muscle fibers?
What about bringing about more definition to the muscle once to the proper amount of bodyfat?
How about raising your heart rate a few notches and burning more calories (not a great amount more...but when shedding fat every bit helps) to help you lean out?
Or doing antagonistic supersets, you don't feel you can do double the work (both bi's and tri's) in the same amount of time you could doing just biceps with the same rest period? You don't feel all the blood inside both muscles at once helps stretch out fascia (again to a small degree) or promote growth?
Or finally, provide an entirely different stimulus for the muscle, mind and body to get used to? When training, anything that requires ADAPTATION=RESULTS. Maybe not what you want or the direction you want to go, but if you do 15 reps per set rather than 6, your body has to adapt it's muscle fibers to that instead what you usually do. That adaptation can be seen as results.
Still think supersets are overrated?
is this post serious? the questions you raise are ridiculous, do you know anything about muscle fiber types, the best stimulus for them? lets look at one question.
What about bringing about more definition to the muscle once to the proper amount of bodyfat?
absolutely not, why would it? david henry does low reps, and straight sets and he has some of the most detailed bodyparts. no exercise will detail a muscle, that is a function of bodyfat, water and genetics, namely the amount of muscle fiber and dominant type.

sure, so can drop sets, rest pause, forced reps, doing so continuously will fry your CNS.

brutal pseudoscience

sure, but all the time no like slintown said, and mixed with other techniques.
you seem to have high amounts of brotelligence. I would love for slintown to give me a scientific explanation on why super or giant sets work better, with some empirical evidence.
