Jake Gyllenhaal was found working out with his friend and co-star in the “Day After Tomorrow,” actor Austin Nichols. His outdoor workout involved jogging, sprints, push-ups, pull-ups and situps. The two were not shy about running and doing floor exercises together.

Obviously Gyllenhaal is not thinking of getting back together with Kirsten Dunst for the sake of their dogs.
