Jeremy Renner Has Bulging Biceps After Superhero Workout

Jeremy Renner shows off his buff biceps in a sweaty tank top while leaving the gym after a workout session on Tuesday (April 8) in West Hollywood, Calif.

The 43-year-old actor is keeping himself in superhero shape while filming his upcoming film The Avengers: Age of Ultron.

Jeremy is back in town after spending a couple of weeks in Italy shooting scenes alongside Elizabeth Olsen and Aaron Taylor-Johnson. So far we haven’t seen any of the other cast members on set, but we hope that changes soon!
