I won't lie to you, this video is kicking my butt. I am on day 2 and my legs feel like they are on fire. I have had to modify some of the moves because of my weight and physical level but I am still getting a kick ass workout and slowly working up to doing every move she does just like she does it. Today I pushed myself to do more than I did yesterday and I am hoping to do the same tomorrow. I'll keep you posted on the results I achieve. The video states you could lose up to 20 pounds in 30 days.
