London's Gymbox in Bank athletic club, recognizing that lifting weights can be a boring way to exercise, introduced "human barbells" recently, hiring five men of various sizes (including two dwarfs) that customers could use for weights instead of the iron. One advantage of the humans is that, on request, they shout encouragement to the customer with each lift. The largest of the five is a 37-year-old, 340-pound man. [Daily Telegraph, 1-22-09]
