That's right, a jump-rope minus the rope. All that's left is two handles, so you jump over the pretend rope. The U.S. Patent Office this month awarded 52-year-old Lester Clancy a patent. What makes this invention work is the moving weights inside the handles. They simulate the feel of a rope moving. But why jump rope without a rope? It's perfect for the clumsy, Clancy said. 'If you are still jumping, you're still using your legs as well as your arms, and getting the cardiovascular workout. You just don't have to worry about tripping on the rope.'
