Pimp My Workout: Train Like a Hollywood A-Lister

Work Out Like: Eva Mendes

The Trainer: Michael Olajide Jr., owner of downtown Manhattan's sleek Aerospace gym, creates supershaping boxing workouts that are a big hit with stars like Eva Mendes.

The Stunt Double: Corinne Iasilli, a 31-year-old film production manager in Sea Cliff, New York, has a goal: "I have closets full of clothes that used to fit, and I want to wear them again."

SESSION 1: A 60-minute Aerobox signature class session: nonstop punch combos and fancy footwork. "I could hardly keep up. I was thinking, 'So Eva has to tough it out like this too?'" says Corinne, whose heart rate monitor recorded a smoking 600 calories burned.

SESSION 2: The gloves are on! Corinne's first-ever boxing lesson, with tons of jabs and crosses. "All the twisting you do throwing punches targets your core, and ducking works your butt and legs, while you're burning lots of calories," Olajide says. "But what attracted Eva was the feeling of power."

SESSION 3: A one-hour lunge date: 60 lunges plus squats with a medicine ball and punching the speed bag.

SESSION 4: Ding-ding! "I was dancing around Michael while throwing punches into his focus mitts, then ducking as he swung the mitts just over my head," Corinne says. Calories burned: 533. "I'm a convert. I finally dropped below 140 pounds and sculpted my upper arms like never before."

Corinne says: "I tried to channel Eva Mendes during series after series of punches, especially as my trainer spurred me on with 'You don't get tired; you get stronger!'"
