THE ROLE Charisa Sosa in The A-Team
WORKOUT PLAN Biel maintains her toned, athletic figure with an active lifestyle and workouts with longtime trainer Jason Walsh. "I keep her within two weeks of being in shape for anything, but we don't obsess," says Walsh, who encourages her to do yoga and hiking between sessions. "Training should be part of your lifestyle, just something you do to maintain good health. That way it's easy to pick up the pace a little when you need to." In the months leading up to filming Biel did a range of circuit and football-like drills with Walsh three days per week. On set she prepared for a post-filming charity climb of Mount Kilimanjaro by hiking alongside celebrity trainer Ramona Braganza.
