Jennifer Lopez is preparing to work out physically to be in shape enough to take part in a triathlon, just several months after delivering twins. The actress was photographed on vacation in Italy this week and it appears she's back in shape, following the birth of her young children Max and Emme earlier this year. Her husband Marc Anthony discloses that Jennifer is on a rugged work out schedule, on foot, on bike, and in water. Reportedly he told a media source, "Jennifer is working out for a triathlon. In October." Anthony concedes he will be viewing from the sidelines, nevertheless.
