Query: What post pregnancy belly?

Jillian gets right to it and then some. I especially like that she does the workout too- it inspires you to work hard. There are two levels: the first you're supposed to do for 3 weeks and then move up to the 2nd level. I'll probably get tired of the same routine before then, but it's nice to have another level to move up to. Bottom line: challenging and nice flow without the dull, repetitive filler. Every move she does has a purpose.
