Jake Gyllenhaal is looking pretty ripped at the moment but his new muscular physique has come at a price, apparently. The actor is currently training for his role as a boxer in Southpaw and is definitely taking the part seriously, training twice a day seven days a week. The 33-year-old is even said to have ended his relationship with 25-year-old model Alyssa Miller in order to devote more time to the gym. "I think he broke up with his girlfriend because he was just in the gym every day. He was training like a fighter. I had him sparring, really getting hit. I put him in situations where I wanted to see what he was made of. No one but fighters understand the sacrifice it takes to be a fighter,"  said Southpaw director Antoine Fuqua.

Fuqua added that he believed that the film is going to change how people look at Jake as an actor.

"I pretty much had him with me and my trainer every day. I took him to almost every fight. I had him train at Floyd Mayweather’s gym in Vegas and we watched Floyd’s fights, and the Manny Pacquiao fight. He trained in New York at Church Gym with real fighters. We literally turned him into a beast… Jake, my god, he’s a very electric, powerful fighter in this movie, and a guy who fights for his daughter. I’m confident that this will change how people see Jake, as a leading man."
