My husband and I have bought this program, we are in week 7 out of 12 and I have already lost 3 dress sizes and 15 pounds.  I feel so much better, I have more energery and I love the workouts.  I will not skip a day.  I will stay with this program into my golden years.  But that's one of the things I love most is that you are not doing the same excersize everyday.  And the food guide is amazing.
