In human anatomy the calf (also calf of the leg) is the back portion of the lower leg. Major Anne Teldy complained about having to walk so far while on a unnamed planet to which Lt. Colonel John Sheppard replied that had he been notified they could have arranged a Puddle Jumper. Teldy's response was that the exercise was good, firming up the glutes and calves. (SGA: "Whispers")
