Jake Gyllenhaal was a changed man after training for Southpaw.
The 34-year-old actor underwent extremely rigorous training to prepare to play Billy Hope, a boxing champion who’s attempting to get his life back on track—but the tough regimen didn’t just transform him physically.
Though he obviously did that as well. Trainer Terry Claybon, who whipped Jake into shape for the film, says Gyllenhaal went from a relatively slight 147 pounds to a ripped 175 pounds in just six months.
