Miranda Lambert's music helps keep the singer in shape, but not just through the calories she burns performing on stage. The country star is sharing her workout playlist with WebMD.com, and one of the tracks she listens to as she exercises is Pistol Annies' "Hell on Heels." Shania Twain's "Man! I Feel Like A Woman" and Carrie Underwood's "Before He Cheats" are also part of her workout soundtrack, along with Kelly Clarkson's "Stronger," Beyonce's "Run the World (Girls)," and Lady Gaga's "You And I." Aerosmith's "Love in an Elevator" and Audra Mae and The Almighty Sound's "Smokin the Boys" round out her list.
