Before filming her new movie, Knocked Up, Katherine Heigl hated working out.

But since meeting Hollywood trainer Harley Pasternak, the actress raves, "I'm in the best shape I've ever been in."

Still, Heigl, one of People's 100 most beautiful in 2007, didn't get there without putting up a fight. She admits:

"I hate dieting. I hate the whole thing!"

A revealing love scene in Knocked Up gave her the motivation to hit the gym with L.A. trainer Pasternak, who is known for his intense, time-efficient workouts.

"Katherine Heigl had a beautiful body, but it had never been toned," Pasternak, who has worked with many celebrities, including Halle Berry, Jessica Simpson and Sheryl Crow, says.

The Grey's Anatomy star, 28, met with him for cardio and circuit-training sessions of 25 to 50 minutes, up to five times a week for six weeks prior to shooting the Judd Apatow comedy.

On-set, she'd jump rope or lift dumbbells outside her trailer during breaks in the action. All the while, she ate Pasternak's 5-Factor Diet, which requires five high-protein, high-fiber meals a day.

Even with a scheduled weekly "cheat day," says Pasternak, Katherine Heigl soon looked "tighter and more toned."

As for the former gym-hater, Katherine Heigl says now, a year after filming, she still works out regularly. "I used to have back pain. Suddenly, my body is supporting itself the way it's supposed to," she says.

"I wake up and I go, 'My god, I can't believe this is my body!'"

A typical Workout for Katherine Heigl:

  • 5 minutes of jump-roping, jogging, or stair-climbing for a cardio warm-up.
  • A circuit of 4 sets each of the following:
  • 25 dumbbell flies
  • 25 lunges
  • 25 low-body crunches
  • 5-25 minutes of cardio running, elliptical training, stair-climbing or biking, with the last five minutes working as a cool-down period.

A sample of her daily meals:

  • Breakfast: French toast with ricotta pillows
  • Mid-morning snack: A mixed-berry shake
  • Lunch: TexMex salad with chicken and black beans
  • Afternoon snack: Hummus crudite
  • Dinner: Sea Bass with brown rice and edamame

Grey's Anatomy Quotes

[narrating] "At the end of the day, when it comes down to it, all we really want is to be close to somebody. So this thing where we all keep our distance and pretend not to care about each other, it's usually a load of bull. So we pick and choose who we want to remain close to, and once we've chosen those people, we tend to stick close by. No matter how much we hurt them. The people that are still with you at the end of the day, those are the ones worth keeping. And sure, sometimes close can be too close. But sometimes, that invasion of personal space, it can be exactly what you need."

MEREDITH

Did you say it? 'I love you. I don't ever want to live without you. You changed my life.' Did you say it? Make a plan. Set a goal. Work toward it, but every now and then, look around; Drink it in 'cause this is it. It might all be gone tomorrow."

Meredith (closing voiceover)
