I just started doing it and I love it. I'm convinced that this is the final step I need to lose the last 15 pounds and tone up. I'm pushing for a tropical honeymoon, so I need to get into bikini shape! Basically I do half an hour each day, 5 days a week. I switch between upper body/abs and lower body. I also do half an hour of cardio everyday. I know some of you will yell at me or something for exercising too much, but I'm used to it and actually cut back a bit. I get fat super easy and I do honestly love exercise.
I suppose I need more ab workout ideas, my gym is lacking in ab machines.
