At 67, actress Susan Sarandon has taken up boxing and regularly practises it to maintain her slim figure.

"Someone gave me lessons as a gift, then I continued, and I like it. I like the gym. It's really fun with all the boxers, and it's fun to hit - it's a workout,` people.com quoted Sarandon as saying.

She also revealed the secret to her youthful appearance.

"If you want to age gracefully, you don't smoke cigarettes and probably laugh a lot, get the normal amount of exercise, eat well and stay out of the sun,` she said.

Meanwhile, the actress is set to welcome her first grandchild later this month when her daughter, Eva Amurri Martino, gives birth.
