This program is the best. I tried two others before. One didn’t do much and the other was so long, I started to resent the time it took. Carolyn’s program is easy to learn and use and the CDs make it even easier. I can easily do the exercises because the CD is always there, counting and telling me what to do next. I only have to devote 15 minutes a day, which I can always do and most of all her program works. I have friends that all want to do this now cause I’m looking so young.
