Jessica Biel [1] continues to have one of the most wanted bodies in Hollywood. So when her trainer, Jason Walsh [2], tells Forbes [3] a few things Jessica does to stay so fit, I am all ears.

Here's the deal [4]:

Jason Walsh, the man responsible for Jessica Biel’s lingerie-clad body in this summer’s I Now Pronounce You Chuck and Larry [5], says that maximizing any workout requires a mastery of the basics.

"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 [6] by Mark Verstegen in order to learn the basics and understand how to avoid injuries.

Squats, crunches and push-ups might need to be added to my list of exercises I can't live without [7]. Though I've got to say, I'm not sure pull-ups are in my cards, even if it means getting one step closer to getting Jess's bod.
