yes bro u should start with 100 ,84 are less

i also want to ask.. how can it possible 84 is for bigging...??

Well that's ok, it's not like you're doing them in one workout, i completed the "Full Body" and 37% of "Legs" but i stopped and i am thinking of doing everything all over again.
So now, you still think 84 Push-Ups are too hard?

Lol of course no u may chose the hard one
