Oprah Winfrey and Bob Greene asked a number of 'Oprah Winfrey Show' (weekdays, syndicated) fans to take the "20 Years Younger Challenge," based on Greene's book of the same name. They followed Greene's regimen for two months, and on Wednesday's episode, Winfrey featured the women, showing the group's "before" picture and then following their progress.

In a pre-recorded clip, Winfrey showed the women working out and talking about their experience. "I have to admit I wouldn't imagine myself at almost 50 wearing a tank top and stretchy pants in front of the camera," said one woman working on an elliptical machine.

There's no way to quantify whether they actually seem 20 years younger, but some of them reported benefits like kicking blood pressure pills. Maybe they mostly feel 20 years younger.

I haven't watched Oprah for years, but I'll be tuning in this week and maybe even recording the shows to watch again later. Why? Because she's got a bunch of shows I can really use!

After admitting to the world that her weight has crept back up to 200 lbs. (although if a celebrity says they weigh 200 lbs., really they weigh at least 220 lbs. - trust me on this), she's getting back on that wagon and taking that fat bull by the horns.

Here's the rundown for her "Best Life Week," day by day:

Monday, Jan. 5: Your Weight. To get back on track, Oprah talks about her diet, workout plan, and ways to put yourself back on the priority list. Her workout guy Bob Greene stops by to help us all out of a rut. I just joined a gym, so I'm completely on-board with this one.

Last summer Anna told you about a new Oprah store that was planned for Chicago. The store has now opened, down the street from her studio, and The Chicago Sun-Times has all the details.

Besides all of the stuff you know you'd be able to buy at the store (Oprah books, O magazine, books by Oprah-endorsed people such as Maya Angelou, Dr. Mehmet Oz and Bob Greene), you can also get $300 Gianfranco Ferre brown crocodile ankle boots, velour jogging suits, and polo shirt/leash outfits for your dog. What, no cars or refrigerators?

Say it's 11 AM; Opie and Anthony's XM show is over and you're looking for something to listen to. So why don't you turn on the channel that's the perfect follow-up: Oprah and Friends!

Yes, kiddies, Oprah and her cabal have started a satellite radio station. But you might have to concentrate hard to actually hear the big O on the channel; according to this article, she will only be on one 30 minute show per week, dishing with her buddy Gayle King about celebrities and whatnot.

What you will hear are the people whose careers O has propped up through her TV show: King, trainer Bob Greene, financial expert Jean Chatsky (mmm... Jean Chatsky), psychologist Dr. Robin Smith, and Dr. Mehmet Oz. Oh, and Maya Angelou gets a show, too (let's hope little Jimmy Norton does a guest shot in an O/O&A crossover). So, it's just like the Oprah show you love, but longer and more self-important. Enjoy!
