Clients like Kerry Washington stay energized by substituting high carb, high fat foods with a diet rich in lean protein and low-calorie, fiber-rich vegetables. These foods not only keep you trim but have an amazing impact on the shape of the body, the appearance of skin, hair, and nails.

You need to stick to a workout that fits into your lifestyle, targets your body issues, but also correlates to your objectives, whether you're at home, on vacation, in the office, or on the road.

It's interesting to work with celebrities; they are very goal-oriented. But they still have to put their shorts on one leg at a time.

I had a client who was getting ready for the Oscars, and all she ate was one meal a day - of two boiled eggs! I was able to persuade her to add some almonds and a protein shake and some vitamin supplements. It's a self-defeating strategy. You need to eat enough, particularly protein, to build lean and toned muscle in the first place.

The Swiss Ball Pike is a total-body exercise that is especially great for your core, arms, and lower back.

The point of workouts are no longer to do double 60-minute sessions or go to classes five times a week. You don't want to burn out and beat your body up.

To me, loving your kids means teaching them to make smart choices from an early age - not just handing over a sweet treat.

The moment your kids start crawling, they are exercising. To them, movement is fun and organic... It is adults who have turned daily activity into a mandatory chore.

Being pregnant is not license to forget all the rules that you abide by when you're not pregnant. Moving your body, getting enough sleep, staying hydrated, and eating proper foods throughout the day are even more important when you're pregnant.

I have never been in a hotel - from the two-star types all the way to five-star - that does not have a gym.

Remember that it's never too late and you're never too old to get the body you were born to have.

I befriend most of my clients, and I like to go out with them. I like to socialize with them: They're interesting.
