Query: Feel the burn

I bought this dvd and got 3/4 of the way through it when I had to stop for the evening. This dvd is a very thorough workout. You're given lots of time to master each isolation as each one is repeated numerous times in various speeds. My muscles burned (particularly my hips and thighs)and I was drenched by the time I was ready to call it quits. Sadie really makes you feel it.The dvd is easy to navigate through like previous reviewers have mentioned. Everything is broken down into categories on the menu so there's no fast forwarding required. The bonus performance is also spectacular. I really love this dvd.
