All of them! I really don't have favorites, I like to train them all.
But I would say training abs is boring, I mostly skip it.
HAHA. i use to be like that with abs. Id go through phases, with ab training, i wouldnt train them for months, then i would go all out,for a month doing 500-1000 crunches a day, yes, it did happen, no vid or pics, so i guess it didnt happen. Lol.
