Summer's Terminator Tune-Up

Summer Glau, star of the new FOX series "Terminator: The Sarah Connor Chronicles" works hard to keep her physique butt-kicking fit - she is playing a terminator, you know - just like her predecessor Ah-nuld, who was pretty buff himself. The actress had her yoga mat tucked under her arm and was clad in comfy yoga pants as she left an Los Angeles workout facility yesterday. Guess her role requires "buns of steel" - literally!
