I live in the #1 agricultural center of the world! Although I don't have a farm (never want one either) I've had pits for over 10 years and believe me I work them. My male is a high energy dog we bike ride for about 6 miles a day either sprinting or him pulling me on a bike. He's got a pack with 10lbs to carry when we walk for another 3 miles; plus all the play time. He sleeps like a baby and snores like a pig.
