28 chimesAfter giving birth to twins Max and Emme in Feb. 2008, Lopez got back in shape by preparing for the Nautica Malibu Triathlon in Sept. 2008. Setting a goal was the key for the actress and singer, who began an intense six-day-a-week regimen of running, swimming and biking for a total for two hours. Recently, the singer has been working out with trainer Gunnar Peterson up to three times a week and when she's traveling, the celeb fitness guru sends her workouts via email for her to maintain.
