I actually brought this video about 6 months ago. I have been using it on and off. Since last week I have been using it every other day and I have noticed a change in my abs. I was in disbelief but estatic at the same time. My daughter is now 14 months and I wished I would have started something sooner. I am gonna give this another 5 more weeks to see if I actually see a big change, my birthday is August 13. I am doing this workout 3-4 times a week and on off days I am doing 30 min. of cardio and yoga. We will see!!!!
