It seems To be the best next level replacement to me. Everybody who does reviews admits it is a kick-@%? work-out but blow it off as not as good as core ball sandwhich and especially Chest, Back & Balls. I'm not looking for a synergistic Chest & Back. I want a next level Core Synergistics.
Feed back Please.

I use Core Ball Sandwich, MC2 Core Syn and Medicine Ball Core Cardio as One on One alternatives. UBB is pretty good but I prefer the other three.
