It looks like Princess Beatrice wants to look great when she is standing next to boyfriend Dave Clark as her personal trainer revealed that the royal is "in great shape."

The 25-year-old has been working with Nadya Fairweather on a weekly basis since 2009 and it seems that the fitness guru actually admires the young royal of York's commitment to her body and is pleased about the healthy approach she is taking to achieving her toned figure.

According to Female First, Fairweather said, "Beatrice is an amazing client. She does plenty of training on her own between our sessions which makes it easier for me to keep challenging her with new equipment and different styles of training."

She went on to say, "Beatrice is in great shape. She eats, which helps. She eats really healthily but she eats, which is massive in a celebrity world full of people starving themselves and doing crazy fad diets which I just do not agree with. Beatrice has beautiful curves and she embraces that."

Shortly after training with Nadya Fairweather, Princess Beatrice wanted to push herself and decided to run a marathon and recently climbed Western Europe's tallest peak, Mount Blanc along with five friends.

Nadya explained, "She decided she wanted to run the marathon so I got her ready for that. That was an amazing personal challenge. She climbed Mont Blanc about a year ago too, she really loved it. She found it so challenging but amazing. She said it was brilliant and she felt fit, which was really good."

When Beatrice is in London she trains for around an hour a week and squeezes in a full body work out into the sessions.

Nadya revealed to the Sunday Express newspaper, "We do a full body workout each time I see her.

"We fit loads into a one-hour session as she has an amazing recovery time between sets of exercises."
