If a person is able to achieve the results they want doing just squats and lunges (lower body), then they may not need pre-exhaust techniques. But for the people that are not getting the results they want, there are physiological reasons for why their programs aren't optimal. And for people that have knee pain, the squats and lunges in huge quantities are a bad idea.
If the exercise isn't causing any fatigue in a particular muscle group, it isn't challenging that muscle group enough. If your quads are burning and your glutes aren't, guess which group isn't being challenged? And, even if you are happy with your rear view, if elevating your metabolism is a goal, maximally developing the largest muscle in your body is a very good idea.
I do squats, lunges and leg presses on a twice a week basis, however, doing them in a class setting is never challenging, except to my knees. Doing them in the weight room, using pre-exhaust techniques really smokes my glutes, tightens my tush, beefs up my backside--however you wanna put it--without causing me knee pain and swelling. I get the best of both worlds.
Again, if you're happy with your results, don't worry about this!! Keep up the good work! If you're not getting where you want to go, or are having joint pain as a result of your current training regimen, give pre-exhaust training a whirl.

BTW, this type of training is for anybody who wants to increase muscularity, improve sports performance or enhance functional strength in a specific muscle group that isn't being successfully overloaded via compound exercises.
