Query: First Week is Tough!

I saw the infomercials late at night which inspired me to order the dvds. I am young, 22 years old, and am in no way overweight (5'7 and 138 lbs) but I wanted to tone all over and lift my flat butt. The guide that comes in the package gets you to evaluate what kind of butt you have and you follow a specific workout for 4 weeks given your butt type. Then the last 4 weeks is the same for everyone. I have done a weeks worth of work outs and by far the "bum bum" workout has been the most challenging for me, it's pretty up tempo and heavy on cardio. I have to pause it a few times and am dripping sweat within 10 minutes! Compared to what others have said, I think the moves are easy to follow and he gives you pointers on how to execute properly. If you think the moves aren't challenging you either aren't doing something right or you are too advanced for theses dvds and should probably do something else.
