Sunday night was a good night to be Helen Mirren.

Not only did the actress, 69, take home the Tony Award for her role as Queen Elizabeth II in The Audience, but she absolutely stunned on the red carpet in a form-fitting white gown with a plunging neckline that showcased her amazing physique.

Although she has a body that women of any age would envy, Mirren has a decidedly low-key approach when it comes to fitness.

“I don’t go to the gym,” she told PEOPLE in April. “I’m trying to go.”

“My thing with exercise is start really easy, just so you only do three sit ups, you know?” continued. “Then do four next week and the next week do five. Start really easy.”

The Oscar winner – who was crowned "Body of the Year" in 2011 – is a fan of the Royal Canadian Air Force’s exercise plan when she gets on a fitness kick.

“I do a thing that leads me into exercise,” she told reporters, according to Yahoo!. “It is the Royal Canadian Air Force exercise plan; it is 12 minutes and they have charts you follow. It is the exercise I have done off and on my whole life. It just very gently gets you fit. “
