Title: Very challenging!
Review: This video is extremely challenging. I own a few Jillian videos and this is by far, the hardest. I have worked out for years, I consider myself to be in pretty good shape, but I couldn't keep up, on either level. There are two levels and you are supposed to move on to the second level after 3 weeks. I took approximately 4 weeks since I only did the video approximately 2 times a week. Even though there are levels, you can still come back to this video when you feel like a complete ab and lower body work out. I was so exhausted from the cardio in the video I found myself cheating and not keeping up, but that's probably the point!
