Let's face it: There are some pretty amazing bodies in Tinseltown. But you don't have to be a star to look (and feel) like one. If you want legs like Jessica Simpson, arms like Jordana Brewster, and abs like Megan Fox, who better to consult than the fierce fitness guru who whips them all into such sexy, stunning shape, himself? Celebrity trainer Harley Pasternak is the man when it comes to sculpting countless A-listers, including Halle Berry, Maria Menounos, Katy Perry, Rihanna, Lady Gaga, and Jennifer Hudson, so we couldn't resist stealing some of his secrets to a Hollywood-worthy bod.

The nutrition pro and bestselling author lives by a simple five-factor philosophy: Twenty-five-minute workouts, five days a week. But make no mistake; this doesn't mean he'll let you off easy. His sessions are super tough but the results are (clearly) worth it!

If having abs of steel is your dream, then "stop crunching!" he says. "We focus way too much on the front of our midsection, which in the process, over-strengthens and draws the torso forward so you end up with shorter looking abs. Focus on lengthening by working your lower back instead. This will give your midsection a full overhaul."

When it comes to legs, Pasternak applies similar advice. "If you want great legs, you need to train them all around, not just the front of the thighs. Use multiple joints whenever possible. And running stairs is one of the best things you can possibly do. It has little to no impact on your joints and you're working your glutes, hamstrings, and quads all at the same time."

And of course, a fit figure wouldn't be complete without amazing arms, to which Pasternak stresses the importance of focusing on the triceps-not the biceps. "When the biceps become too strong, it brings the shoulders forward and makes for a gorilla-like posture. Another mistake women make is using too light of weights. You won't get big muscles with big weights!"
