Sandra Bullock has barely aged during the past 20 years, thanks to a healthy diet, daily workouts, and an active lifestyle.
The 5-foot-7 brunette beauty does a combination of cardio exercise and strength-training to maintain her stunning, age-defying good looks.
"I do a lot of Pilates, kick-boxing and weight training in L.A., and when I'm in Austin [Texas], I run or ride a bike," Bullock, 49, told Vogue.
Sandra, who has always been fit, said staying in shape isn't difficult because it's her job to work out and look good. "People ask, 'How do actresses do it [stay in shape]?' " she said. "Um, they pay us to do this in order to look good on film."
In recent years, Bullock has incorporated plyometrics and an hour-long routine that combines yoga and Pilates with dance cardio into her workout routine. The new regimen is clearly working, judging by her buff arms and toned torso.
Sandra puts in an hour a day [at the gym], six times a week. She is extremely motivated and driven.”
While celebrities such as Melanie Griffith and Meryl Streep have slammed Hollywood ageism, insisting actresses stop getting job offers once they hit 40, Bullock's career is on fire even as she approaches 50.
In 2010, Bullock won an Academy Award for the drama "The Blind Side," and her cop-comedy, "The Heat," has grossed over $228 million worldwide since its June 2013 release.
Her latest film, "Gravity," has grossed $285 million at the worldwide box office since its Oct. 4 release. To date, Bullock's films have earned over $2 billion worldwide.
Bullock enjoys her success, but says becoming a mom has had the most profound impact on her life. Bullock adopted a baby boy named Louis in 2010.
"Everything becomes richer or more important or more frightening or more challenging [after you're a mom]," she said. "You feel like you were dead compared to the way you were emotionally before."
