Hi.
Yes, I believe MIC is the hardest video (cardio or other IMO) I have ever done. It's harder than the two IMs because there are literally no breaks once she gets going. At least in the IMs, you get breaks after the really intense stuff.
The Low Impact routine is pretty easy, and the Medium Impact isn't really too bad, but once she gets to the High, watch out because not only is it extremely intense, there are no breaks. None. The intensity is way up through the whole thing.
Then you get one little break before the Step portion. And again, the step work is extremely intense, no breaks. Then when you think you are about to keel over she throws in that five minute intensity blast at the end.
It is a KILLER. I have every Cathe workout and so far killerwise, MIC has yet to be outdone, IMO.
I'm a little worried about that Kick Punch and Crunch video coming out soon. I read where some people think it's the hardest video Cathe's ever done. If it's harder than MIC, "oh my," is about all I can say. }(
I like doing it though because it makes me feel really really STRONG to be able to do it.
And I definitely feel great after I am done.
Hope you enjoy it!
Melanie
