Just for giggles, I'm going to argue that you not get it. I have found Boot Camp to be rather useless. It's not really cardio, due to the very short bursts and long breaks in between, it's not really a leg workout, it's not really tough upperbody. The abs are very good. I have used it a bunch while riding my stationary bicycle. It is superb for that. I do intervals during the cardios, leg drills during the legs and ride steady during the upper body and abs. The time flies, but as a regular workout, not too useful.
Muscle Endurance is a lot like PowerHour. I'm with the majority in that I think PowerHour is maybe 20% harder, with two exceptions. The biceps and abs work are really tougher in ME. In fact, I think the abs in ME are the toughest she's ever made.
But if you have Powerhour and the abs from PUB already and you don't have money to burn, you could live without this and just buy the BodyBlast.
I use ME and BootCamp but less than the other tapes and they are just not that "intense".
