Jake Gyllenhaal's new boxing movie "Southpaw" comes out July 24.
Gyllenhaal trained like a madman to convincingly pull off the part of boxer Billy Hope. Before getting jacked for the film, Gyllenhaal lost 30 pounds for his role in "Nightcrawler."
The transition from that physique to his one for "Southpaw" is nothing short of stunning.
Here's a side-by-side comparison of Jake's different bodies:

To make this shift, Jake was in the gym twice a day, every day, and he completed 2,000 situps a day. He was joined by the director of the film, Antoine Fuqua, on his boxing odyssey. Fuqua trained just as hard as Gyllenhaal as a show of solidarity.
All of this hard work really paid off as Gyllenhaal was able to gain 15 pounds of pure muscle for the role.
Now, Gyllenhaal is totally ripped.
