As usual, Wii Fit was born of one of Miyamoto's hobbies. Seeking a new, healthier way to relax, Miyamoto quit playing pachinko and took up swimming. He then started graphing his weight daily. This was the basis for the "Wii Health Pack" project, which, at first, didn't have any design specs except measuring weight on a graph. The actual game, then, came from the need to integrate exercise with a device that measured weight. This began with an experiment with balancing on two scales.
The old rumor that Nintendo would be designing a new Balance Board for our big American clown feet is also called into question by the fact that Reggie and other large-footed staffers were brought in to test the Japanese board.
