Robert Pattinson hit the gym in Hollywood yesterday with his female personal trainer. The actor has been making exercise stops quite a bit in recent months, possibly to beef up for his upcoming role in Mission: Blacklist. This is the first public outing for the actor since new photos surfaced of Rob meeting up with Kristen Stewart in LA last week. Kristen Stewart was spotted driving her blue truck with a man who looked like Rob following closely behind in his white SUV. The former couple reportedly spent time together at Robert's home in Beverly Hills. It isn't clear if the meeting was just a friendly one or if there is some hope of reconciliation for fans. Rob and Kristen broke up back in May after rekindling their romance last November. The two have been dating off and on since 2008.
