Pimp My Workout: Train Like a Hollywood A-Lister

Work Out Like: Queen Latifah

The Trainer: Jeanette Jenkins, longtime trainer of Queen Latifah, helped the star slim down by 25 pounds and stay fit ever since with a fresh routine each month.

The Stunt Double: Talie Grill, 30, a marketing coordinator in Los Angeles, admits that her gym routine has been more off than on lately: "I get bored with exercising after a few months and gain back the pounds all over again."

SESSION 1: Six times up and down the Santa Monica stairs -- almost 2,400 steps -- mixed with crunches and push-ups. "There's no phoning in the push-ups in front of Jeanette," Talie says. Why? "Nothing motivates you more than results, so don't cut corners," Jenkins says.

SESSION 2: A three-mile run through Beverly Hills -- "My calves were toast by then," Talie says -- plus 200 reps of ab exercises.

SESSION 3: Circuits at Fitness Factory L.A. in West Hollywood, alternating a little bit of everything, three sets of 25 reps each.

SESSION 4: A boxing and rope-jumping workout at the Gym on Nemo, a private studio in West Hollywood. "The key is to find things you love to do," says Jenkins, who varies Latifah's sessions.

SESSION 5: Ashtanga and Iyengar yoga at Jenkins' studio. "That's it! I'm done with my usual gym drill: upper body one day, lower body the next, then cardio," Talie says. "I'm switching to yoga now and the same exercises Queen Latifah does, from Jeanette's workout DVDs."

Talie says: "I want to be as strong and body confident as Queen Latifah is. But man, am I sore."
