9. Log On for Success
Share the same workout advice as Jennifer Aniston, J.Lo, and dozens more celebs at podfitness.com, which offers "trainer in your ear" programs from more than 75 experts on everything from weight loss to walking.

10. Train for the Finish Line
Singer Sheryl Crow regularly cross-trains with a combo of running and cycling. In addition to regular jogs, she's prepping for a 100-mile bike ride by cranking up the resistance on a stationary bike until she can barely pedal, then bringing it back down, says trainer Greg Bahnfleth.

11. Mix Things Up
"Every day should be something a little different when it comes to your workout routine," says trainer Michael George, who has worked with Reese Witherspoon, shown here, jogging. "Otherwise, your body gets bored and you stop seeing results."

12. Band Together
Julia Roberts stays in shape with do-anywhere resistance-band exercises from trainer Kathy Kaehler, including standing on the band for double biceps curls and front and lateral shoulder raises.

13. Run for a Cause
Meredith Vieira often participates in charity run/walks that help raise funds for everything from cancer to mental health. Want to join a fun run? Check out these options.

14. Nix Boredom
Kate Hudson keeps fit by mixing things up. In addition to running, she takes Sheila Kelley's S Factor (pole dancing and striptease) classes regularly -- in 6-inch heels!

15. Ride On
Madonna should wear a helmet while she rides, but even so, cycling is a great way to cross-train, burning more than 500 calories an hour at a moderate pace and sculpting the abs, legs, and butt.

16. Shake It
Nikki Blonsky, just 18, loves dancing and adored training (hard!) for her role in the movie Hairspray. She told FITNESS that at one point, she was losing weight so quickly she had to drink protein shakes to stay at her character's size.

17. Be Fluid
"Drinking before and at frequent intervals during your workouts prevents dehydration, cramps, and overheating," says Pilates expert Daniel Loigerot, who works with Naomi Watts. For more hot-weather exercise tips, see our "Love Your Summer Workout" story.
