Taking the plunge: the actress made an appearance at the Hollywood Awards [Agencies]
Although Miss Zeta Jones is not known to be an exercise fanatic, she is a regular gym goer and recently added weight training to her list of skills.
On top of this, she is an excellent golfer and often plays on the course alongside her husband of seven years.
She has, however, previously claimed to detest dieting and insisted that she only eats when hungry.
Talking about the Hollywood obsession with weight, Miss Zeta Jones, a former West End dancer, said: "My muscles have memory from the time I danced, and it's quick for me to get back in shape, but I'm not fanatical."

"I grew up with dancers, anorexia and other disorders were common, so I learned how to deal with [diets] without losing my limit.
"I think it's awful, this competition in the U.S. between actresses who just had a baby, to see who's first to get back to their normal weight. It's insane. I find this wave of super-skinny women scary."
Ms Zeta Jones and Mr Douglas, who have been in Bermuda competing in a golf tournament, took time off the green to make an appearance at the benefit.
