"Denise Austin practices what she preaches," said legendary fitness enthusiast Jack LaLanne, who gave Denise her a first big break on his show. And it's true... Denise works out just 30 minutes each day ("I really try to make the 30 minutes very effective and efficient because I don’t have a lot of time.") and eats healthily but indulges a little too ("I eat well 80% of the time and have my treats 20% of the time"). In her just-released book Get Energy! Empower Your Body, Love Your Life, 53-year-old Denise Austin shares the food and fitness plan that's allowed her to maintain her booming body and her booming business for the past 30 years.

The book has a quiz to help readers identify their own energy-zappers, a list of energy-boosting foods and guidelines on when to eat them, mini-workout routines and more.

"I wrote 'Get Energy!' because I meet with women all the time who ask me, 'Denise, how do you have so much energy?'" says Denise. I compiled the tips and stretches that I use throughout the day to stay energized and fit!

Denise's workout bible has already received glowing reviews: "Denise Austin makes the Energizer Bunny look lethargic," wrote People magazine editors. "Denise Austin probably could motivate a statue," said a review in the Chicago Tribune.
