Even with one of the best bods in Hollywood, Halle Berry still needs help when it comes to staying in superhero shape. Harley Pasternak has gotten the naturally fit star ready for big roles in Gothika, Catwoman and Our Eyes Are Watching God. The two are currently working toward getting her back into superhero form for the upcoming X-Men 3.

Pasternak is the first to admit that Halle, like most of us, isn't a fan of working out. "Halle is amazing," he says. "She's naturally pretty athletic, having been a gymnast when she was younger. She does not like to exercise, but she definitely knows she needs to, and it's a means to an end."

It's hard to believe that someone with a practically flawless physique could dislike working out. But Pasternak says for Halle it's all about the end product. "She has no problem working her butt off as long as she doesn't have to do it for too long, and as long as she sees results."

To keep Halle happy and motivated, Pasternak keeps her workouts short, intense and effective. And even though she always stays on 5-Factor to some extent, Pasternak says her routine changes depending on which movie she's working on at the time. Sometimes she'll be training five days a week for 30 minutes a day, and other times she'll cut it down to three times a week.

"In Catwoman there was a special need for her to be ultra-fit and very lean and very strong," he says. "And in Our Eyes Are Watching God, we had to kind of let it go. You know, really had to let her be less toned and a little looser."
