Query: Great Workout!

I have heard good things about Mrs. Michaels, and I was proven right when I decided to purchase this DVD. I just started it today actually. It for sure had me sweating a storm.I love her no-nonsense and fun upbeat personality. Today I almost gave up, but decided to go on and felt great when I finished. I realized I am beyond level one and can actually step up to level 3. I am going to do this 5 times a week along with Turbo Jam to get maximum results.
