While her friends lazed about in the sun, the 37-year-old balanced on one leg and held herself in the plank position. Other yoga devotees include Madonna and Uma Thurman who have credited the Indian technique for their toned physiques.

Diaz has said in the past that she hates the gym, so tries to stay active outdoors instead. "I hike, snowboard and surf. I admit I do hire a personal yoga trainer as well, but for me working out is a big part of keeping mind and body together," she said. The actress has taken up yoga in a big way and trains three times a week with an expert.
