Will 400 situps a day give me a 6-pak?

u dont have to do 400 sit-ups. u'll get the same results if u do just 100-200 sit-ups. just keep doing that every day and u shuld start seeing results within a couple of weeks, i think. idk for sure. diff ppl get diff results in diff time. srry for not having an exact answer or nething. its the best i can do for u. :(
