Celebrated Brazilian beauty Daniella Sarahyba shares her supermodel secrets.

Twenty-two-year-old Daniella Sarahyba may have “supermodel” written in her genetic code (her mother was a celebrated model in the 1970s and ’80s), but that doesn’t mean looking good and staying fit always come easy for her.

“With all the traveling I do, it’s very hard to have a regular workout routine,” says the Rio de Janeiro native. “So I try to do activities like walking and yoga that I can do almost anywhere when I have the time.

The key for me is keeping the workouts fun and flexible.”

Jennifer Poulsen, a fitness manager at the 24 Hour Fitness in Arnold, Missouri, shows you how you can create your own version of the supermodel workout.

The Model Way: When I’m in Brazil, I drink coconut water, because people say it’s good for the skin,” says Sarahyba. “I generally try to eat a healthy diet, and one thing I’m really careful about is not eating carbohydrates at dinner.

It’s too late, and I never feel good the next day if I do that.”

What You Do: The math. “When you boil it down, weight loss is really just a simple math equation,” says Poulsen. “If you burn more calories than you take in, you lose weight. Problem is, most people don’t understand how much they’re taking in.”

Keep a calorie-counting journal, and you’ll quickly gain perspective on the big picture of your nutrition habits. As you journal, monitor your protein intake-that goes for guys, too.

People losing weight often lose muscle mass by not taking in enough protein to support what they’re doing at the gym.

The Model Way: “I work out to get just a little definition, so that I have simple lines,” says Sarahyba. “I don’t want big muscles; I just want a toned body that looks natural and beautiful.

I think it helps that I like to do exercises with free movement and power, like shadowboxing and yoga, and I’m hoping to try Pilates, because it looks perfect for me.”

What You Do: Total-body toning. “If you want a smaller [and flatter] stomach, you don’t go to the gym and do 500 sit-ups,” explains Poulsen. “That’s called spot reducing-and it really doesn’t work. A well-rounded, total-body workout is really the key.”

That’s where circuit workouts come into play, toning muscle groups you want to show off on the sand while keeping your rate of calorie burn high.

The ideal circuit workout consists of a low-weight, high-rep routine that hits as many muscle groups as you have time for, with no rest between sets.

Poulsen recommends incorporating three circuits a week into your gym routine. Make sure to mix up the elements of the circuit every 4 to 6 weeks as your muscles adapt to the stress.

The Model Way: “I’ve tried a lot of different things to find what I like,” says Sarahyba. “I had a personal trainer, and we worked with weights in the gym. It helps to try everything to find the things that you like to do.”

What You Do: “A lot of the challenges people face are individual, and they require individual solutions,” says Poulsen. Almost any gym provides to its members 1 hour of free consultation with a personal trainer.

Use that hour to find out what you like, what you don’t like, and how best to prepare for and achieve your own fitness goals. [source: You24]
