Gyllenhaal -- who is shirtless for half the film (out May 28) -- joked to Us about his workout routine, "Shampooing and conditioning. Not the 2-in-1. Shampoo and Conditioner; vigorously rubbing, rinse and repeat, biceps, triceps, physique!"
A source told Us that Gyllenhaal was "very proud of the way his body looked" after intense cardio and power circuit training.
"He was constantly shirtless," the source said.
Gyllenhaal even stayed in character off-set.
"Jake would chat with crew and visitors in a British accent," said the insider. "It was funny to hear this American guy talking in an accent when he wasn't shooting. He took it very seriously."
