for bball I've had people recomend me do it twice a day and this is not comming from one person or just some joeshmoe, I think if you train them hard though, 4-5 times a week is enaugh
I guess its all for different purposes, but I'm not gonna argue about this cause you guys sure have a different opinion on this
P.S I cought a small part of this show on BET about a year ago and they were talking about usher and how he needs to maintain his body so he does 200 situps every night and some other stuff
I dont know though, maybe bodybuilding has a different purpose for abs or something but I was kinda shoked when I came here and people tell me its stupid doing abs more than twice, maybe cause you guys are hella concentrated on your diets
