Query: Great workout

I am a die-hard Jillian Michaels fan. I have four of her DVD's and use them on a rotation basis (with some other videos thrown in on occassion). Her videos make you feel as though you want to die, but in the end, it's all worth it. By the end of the first month, these videos do not seem as hard as the first time around. This video is great because it not only gives a great cardio workout and everything else you expect from her videos, but it also specifically targets those areas that every girl wants to tone but has trouble doing (hence the name of the video!). I would definitely recommend this video to anyone who asks. But be warned- it's not for the faint of heart- it's for those that really want to make change happen.
