Looks like Gisele Bundchen had an extra hard workout at the gym in LA yesterday! She wore leg warmers for the sweat session, which helped maintain the amazing figure she showcased in a sexy spread for April's Vogue Paris. As March comes to a close, Gisele is sticking to a casual routine in California, but the month kicked off with a wild trip to Brazil where she celebrated Carnival with husband Tom Brady and the QB showed off his hot dance moves. Gisele turned her focus from fun to an important cause when she participated in Earth Hour over the weekend. It's a cause so close to her and Tom's hearts that they even observed it at her sister's wedding last year.
