Jillian Michaels: 6 Week Six-Pack
Best Ab Workout DVD
Jillian Michaels' no-nonsense fitness philosophy on "The Biggest Loser" and her DVDs has earned her a big following in recent years. In this video, Michaels promises a flatter, more-toned midsection in 45 days. The two 30-minute routines are challenging, and while they can't guarantee that everyone will have washboard abs in six weeks, reviewers say if you stick with the program you'll see results.
