Jillian Michaels on exercising her staying power

(CBS News) Having exercise equipment in your home doesn't do any good unless you use it, which is where the "biggest winner" in the home fitness business comes in. Ben Tracy has tracked her down:

Jillian Michaels says it's a bit embarrassing to see her face and name on all of the products in her office.

"It feels so cheesy, like the Andy Warhol photo of yourself on the wall," she told Tracy.

But it also makes her feel something else: "Sometimes I'm, like, this room is not big enough. We should be doing more."

"More" might as well be Michaels' mantra. She's the biggest name in at-home exercise, a bestselling author, and a ferocious force for fitness on the reality TV competition, "The Biggest Loser."

She's now at the point where people consider her a brand.

"Oh, I definitely think of myself as a brand," Michaels said. "But I'm not going to sell you any false promises, and you may not like the message. You may not like the things I'm saying. But at the end of the day, you're going to like the end result."

Her direct approach is now legendary. It's "tough love" that often seems to lack the "love" part.

When asked if what we see on "Biggest Loser" is an accurate representation of who she is, Michaels replied, "It's an incomplete representation of who I am. There are plenty of tears, there are plenty of in-depth, heartfelt moments. But the yelling makes better TV."

"How has the persona you've developed on reality TV hurt you?" Tracy asked.

"Wow. Okay. I've always wanted to shift into a daytime medium, But everybody who's kind of in charge of that daytime medium doesn't really know me, doesn't really watch the show, isn't that familiar with what I do, and just goes, 'Oh, she's the girl that screams on TV. She's unlikeable.'"

Yet plenty of people DO like her. She's released 15 home fitness DVDs, selling 8 million copies. She's written six diet and fitness books, secured countless product deals, and is about to launch a nationwide speaking tour.

Michaels now heads a multi-million-dollar exercise empire, but says she has no time to actually exercise. "I honestly haven't been to the gym, because of my schedule, in several weeks," she said.

"I don't think people are going to believe that," said Tracy. "They picture you at home in your gym eating kale all day."

"Oh God, no," Michaels said. "I practically drank wine out of the bottle last night, I was so stressed out. And I had to,like, handcuff myself to the couch to not have ice cream for dinner."
