Get ready for lean mean fighting machine Miles Teller. While we’ve seen a peek of his body in the one photo released so far from his upcoming drama Bleed for This, it sounds like he went through quite the physical transformation for his role as real-life boxer Vinny Paz. While promoting Insurgent (in theaters on March 20) Teller told E!, “When I started training I was like 18 and like 18 percent body fat. I got down to 168 and six percent.” That was for his first fight in the movie, but in the film, Paz actually goes up three weight classes. Teller said, “For the last fight I was at 183. So I gained 15 pounds in like two and a half weeks.”
