Reese Witherspoon  brought her boyfriend Jim Toth along yesterday for a jog near her LA home. She had the weekend off from working on Water for Elephants  after logging time on set last week  with costar Robert Pattinson . Rob, meanwhile, was busy taking care of business at the press junket  for Eclipse  in Beverly Hills. It looks like Jim is following in the tradition of Reese's last boyfriend, Jake Gyllenhaal , by joining her for a couple's workout . He took things one step further by wearing a LiveStrong shirt similar to the one Jake sported  for a sweet and sweaty exercise sessions with Reese in 2008.
