Jennifer Garner [1] is one busy woman. The actress showed off her fit figure after getting her workout on in LA on Wednesday. Jen, who wore black pants and a blue shirt for the sweat session, was her usual perky self as she strolled down the sidewalk while laughing with a friend.

The outing is just the latest we've seen of Jen's bubbly personality in recent months. In addition to flashing her infectious smile [2] in LA, she also enjoyed some quality time [3] with her daughters, made a sunny appearance in London [4] during a family trip, and got friendly with her ex, Ben Affleck [5].
