Gossip Girl star Leighton Meester swears by "a week of really great cardio" to flatten her stomach.

How much cardio should you do? An hour a day can make a difference, says Ashley Borden, an L.A.-based celebrity trainer.

Do you think an hour of cardio for a week sounds overwhelming?

Who wouldn't love to have Gwyneth's gorgeous body? If you're willing to workout for three hours daily, you've got a shot.

"I think she works out three hours a day - which is one of the keys to success," chef Mario Batali told Usmagazine.com at the opening of the Uncle Ben's Kids Café in Carson, California, on Wednesday

"If we all did that, we’d all look like Gwyneth Paltrow," he said. "Or at least closer."

He added that the Iron Man actress, 35, "loves to eat ... and, you know, she never puts on a pound!"

Paltrow and Batali are teaming up for their upcoming PBS documentary Spain ...On the Road Again, airing this fall.

"We had an amazing time — we saw everything!" he said.

"Predominately," he added, the show's "about understanding Spain from the perspective of a casual traveler. It’s very much like a road trip, we just drove into a place, figured out what was going on and tried to get a hold of it." SOURCE

Most people think they need a gym membership to stay in shape, but I know otherwise. Why exercise in a stuffy gym during the warmer months? Instead take advantage of the beautiful weather by exercising outdoors like singer Alicia Keys.

"I like to do outdoorsy things," she says. "Hikes, trails, running, swimming. I love the sun. I'm all about the warmth," She told People.

Need ideas?

• Go for a power walk or jog around the neighborhood.
• Swim laps.
• Play jumprope or hoolahoop with the kids.
• Bring your yoga mat outside to practice your favorite poses in the sun.
• Take a nature hike.
• Bring your free weights outside for a session of lunges and squats.
• Ride your bike instead of driving to local errands like the post office or starbucks.
