Mischa Barton is planning to get back into shape. The actress is currently in New York City to shoot the TV show A Beautiful Life. And when she’s not busy filming, Mischa has been hitting the downtown Equinox gym and has even hired a trainer. “Mischa is really focused on getting into shape,” a source told People mag. “Mischa has been doing a lot of conditioning with weights as well as cardio on the treadmill, and some kickboxing. “She’s been very consistent and she seems focused.” “She has big self-esteem issues,” a source said last month. “She hates her legs. She isn’t comfortable with her body. It’s been a big source of stress and self-hate.”
