Nowadays, you can keep up with almost everything that your favorite actors and actresses are doing. Between Twitter, Instagram, Facebook, and Vine, there's more sharing than ever, and in turn, there's more personal details about celebrities available than we could've ever imagined. We know what they ate last night, who they've been hanging out with, and what clubs they've been partying at.

What about how they work out: what gear do they bring along, what music do they listen to, and what workouts are their favorites? While we can't say for sure, we can learn a lot from their paparazzi snaps. Actors have to stay in shape too, and whether they're coming to or from the gym, they often fall victim to the flashing lights of the paps. We tried getting names like Channing Tatum and Matthew McConaughey on the phone, but they were too busy filming their latest blockbusters, so we took it upon ourselves. This is How 10 Actors Workout, According to Their Paparazzi Pictures.

Funnyman Jonah Hill is all business when it comes to his fitness goals. His inspirational weight loss had Hollywood buzzing, and he's still going hard on the regular.

After working in a variety of roles over the years, Jared Leto's weight has fluctuated depending on the character, but for the most part he keeps it lean and slim.

The GG 2013 Man of the Year has come a long way since his burnout character in Dazed & Confused, and although his True Detective character is one of the most intense on TV, he still strikes us as a  pretty easy-going, laid back type of guy who would have an extensive country collection on his iPod. After all, one of his very first roles was in a 1992 country music video.
