Julia Roberts Really Does Exercise To Stay Fit And Sexy At 42

Julia Roberts graces the cover of September's 2010 Elle magazine. She is also featured in a wonderful photo lay-out in the fashion mag. Here are two pics from that shoot. And looking fab at 42!

How does the star of the summer hit movie, Eat, Pray, Love always look so together and svelte? And still stay that way after having 3 kids?

Seriously, we never thought that Julia Roberts did any exercise at all. We just assumed that the movie star was really pretty, naturally slender, and gifted with a tall, legs-up-to-her-neck kind of figure.

Boy, were we wrong! Julia Roberts has had the same trainer for almost 15 years now. She is celebrity favorite--Kathy Kaehler. And according to Kathy, Julia loves step aerobics and spends about 1 hour, 3-4 times a week with her, working out:

"Eat Pray Love took her all over the world but when she got back [to California] I helped her get ready for the press tour," Kathy Kaehler tells Elle. "We currently do 20 to 40 minutes of step aerobics and up to 40 minutes of body work—lunges, crunches, planks, push-ups—after.".

And Julia admits she isn't wild about exercising, but likes the strength and rewards from a work-out routine:

"Sure, there are days when she doesn't feel like stepping, but once she starts, she loves every minute and feels refreshed after," Kathy explains.

Julia Roberts admitted that she gained about 10 pounds while filming Eat, Pray, Love in Italy, but those lbs. melted away by the time she strolled the red carpet to promote the movie.

According to her trainer, she got back to eating sensibly and the good habits that go with a sound diet. "She is a great cook and uses only organic or home-grown foods for her family," Kathy Kaehler says.

So there. A little step, a good life, and some healthy organic stuff tossed in, and you get the secrets to Julia Roberts' staying fit and sexy at 42
