Helen Mirren maintains foxy figure with Nintendo Wii Fit

Helen Mirren claims that her secret to looking young is holding in her stomach and wearing platform high heels.

But now that she's shilling for Nintendo's Wii Fit, she's got another fitness trick up her sleeve.

"The Wii is fun, and it's infinitely varied. You can hula, jog, yoga, step, all in one session, she said, according to the Daily Mail. "You need never get bored as every day you can tailor a new workout.

"It challenges you, and you do it at home, so nobody need see you in those old yoga pants and torn T-shirt."

The 65-year-old Oscar winner, who famously posed nude in New York magazine this year, has claimed to be as body-conscious as the next woman.

"Holding your tummy in is another trick for making you look and feel good," Mirren said. "I don’t know why, but I do, by nature, hold my tummy in."

Bits of my body are all right, but bits of me are horrible," she told Woman and Home last month. "To be honest, anything from the waist down I don't really like."

Mirren recently gave 24-year-old actress Megan Fox a run for her money, nearly beating her out for Esquire magazine's 2010 Sexiest Woman Alive. She told the magazine that she was "gobsmacked" by the honor.
