Einar uses a power drill
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Einar decides to tape the pedometer to the end of a drill so that it will spin round really quickly. He attaches the pedometer successfully, and keeps hold of the drill while wearing a hat. He turns it on and holds it for the full 90 seconds, talking periodically about how tiring it is. The pedometer measures 612 steps and Einar earns first place.
