Query: Great workout - almost too much

I'm sure that by the end of my 30 days I'll be shredded. In one respect, I'm already seeing the results in my first week. Jillian pushes me hard but positively. My only warning is that you warm up a bit more that Jillian does. I felt so much better doing the workouts when I had spent my own time stretching as the dvd started up. Overall, a great buy, though.
