different reps for different body parts?

[DONALDuckY]

Sorry for such a newbie question, but I know that i should do a reverse pyramid set while increasing weights on my chest, but do i use the same idea for all my other body parts? Does it all depend on whether you're working out major body parts?

that isnt the only/best way to work your chest, its just what works for a lot of people, you gotta find what sets work for your body and that will be your answer
