Jessica Biel has an amazing body. She is a great role model for women who want to get in shape and still look feminine. Her trainer Jason Walsh recently revealed her workout in People magazine...showing how she manages to get such an incredible body.

Were you lucky enough to see Jessica Biel in the movie Blade 3? If you did, you may have seen fitness perfection. Seriously...Jessica looked amazing in that movie. As a side note, Ryan Reynolds got in amazing shape as well. The great thing about Jessica Biel is that she manages to stay in amazing shape without losing her femininity.

Here is an Outline of Jessica Biel's Workout, With My Comments

1) Cardio...She does Interval Training. Here is a quick summary. She jogs for a 1/2 mile warm up and then does 6 sprints with short rests in between. She does 2 sets of 200 meter sprints, 2 sets of 150 meter sprints, and 2 sets of 100 meter sprints.

My Comments: This is the best form of cardio to really burn stubborn body fat quickly. High Intensity Interval Training has been shown to burn significantly more body fat than steady state aerobics.

2) Plyometrics..."These hurt," says Walsh of stair jumping. "Even athletes hate them. After Jessica did these the first time, she would've punched me if she had the energy." How-to: Jump from the bottom step of a flight of at least 20 stairs to the third. Keep going, skipping a stair each jump.

My Comments: Plyometrics are an athletic way to tone the body. I believe that athletes have better looking bodies than people who only spend their time in the gym. I understand why her trainer, Jason Walsh, would recommend them.

3) Weight Training..."We tend to use lighter weights and do more reps," he says. "We keep moving, so it becomes a cardio workout too."

My Comments: This type of circuit training is outlined extremely well in the book by Craig Ballantyne, Turbulence Training. He isn't a big believer in cardio and has a workout where people get ripped by resistance training alone. Jason Walsh, combines cardio along with this type of "Turbulence Training" workout.

4) For the Abs..."Hanging leg raises don't build a six-pack, but they flatten," says Walsh. "Jessica hates them, but she powers through!" They also do the Russian Twist. Sit down and lean back slightly. Hold a 5-lb. medicine ball and twist from side to side, 15 twists per side, three reps.

My Comments: I don't agree with this approach to developing the abs. The problem with hanging leg raises is that they shorten the hip flexors which can dramatically increase your chances for injuries. I am a big believer in a great exercise called "planks". Not only are they effective...they help protect your back from injury as well.

So in Summary...It really looks like Jessica Biel's Workout focuses on Interval Training both in her approach to cardio as well as her weight training.
