To the average gym-goer, attaining a star body may seem daunting if not altogether impossible. The sculpted abs, toned arms and shapely legs that float by on the red carpet often look like the product of good genes, a starvation diet and never-ending fitness boot camp.
But celebrity trainers say such a look is attainable without spending a sum on one-on-one training or spending untold hours on the treadmill.
"It is all within your reach," says Gunnar Peterson, whose clients have included Jennifer Lopez, Gwen Stefani and Matthew McConaughey. What's often most challenging, he says, is first getting off the couch.
To that end, instead of playing the drill sergeant, trainers help their celebrity clients develop a fitness regimen they can look forward to, find ways to maximize the gains and push them to meet their goals everyday.
"It's about the mental fulfillment," she says. "If you're going to make someone do something they don't enjoy, they won't want to do it again."
Simmons, head of the Baby Phat empire, trains with Jenkins four days a week for an hour at a time. Jenkins advocates a circuit training program, which improves cardio and strength simultaneously, in combination with cardio-heavy activities like boxing, hiking or jogging.
"Kimora likes to work her legs," she says, "so I've created programs with interval boxing--something she enjoys--mixed with leg exercises."
While it may seem like celebrities exercise obsessively at least four or six days a week, the government actually recommends at least 30 minutes of moderate exercise most days of the week. At optimal levels, Americans would sweat through a 60 minute workout regularly throughout the week.
"Learn how to squat properly, crunch properly and how to do push-ups and pull-ups--two of the best upper-body exercises," he says. In addition to a weekly three-day cardio regimen, Biel spends three alternate days focusing on muscle development and toning by doing lunges, crunches, squats and core work.
Walsh suggests that beginners hire a trainer for a month or pick up a book like Core Performance by Mike Verstegen in order to learn the basics and understand how to avoid injuries.
Trainer Gunnar Peterson maximizes the workouts of his clients with a "buy one, get one free" approach.
He recommends holding dumbbells while doing leg lunges or using a medicine ball while doing crunches. While recently training a client who was readying for a tour, music video shoot and album debut, he combined exercises like crunches with a medicine ball in addition to footwork and sprinting on an outdoor track.
