Pictures of Jake Gyllenhaal Jogging

Jake Gyllenhaal wore a tank and short shorts for a run in the Hollywood Hills with Michael Peña yesterday. The buff buddies are costars in End of Watch, and they'll soon welcome a new member to the cast since Anna Kendrick just landed the role of Jake's onscreen wife. Jake and Michael have already been spotted in uniform on set, and it appears that they're continuing to work on their physiques for the roles. Jake had another running companion earlier this week though, when he went for a jog with his brother-in-law Peter Sarsgaard. Both guys sported '80s style gear for the workout session, which they followed up with lunch near Venice Beach. Peter is in town to promote Green Lantern, and he stepped out on the red carpet alongside Blake Lively and Ryan Reynolds at the film's premiere last night.
