Turns out that the same technology used in Personal Trainer: Walking to train you will also help you train Pokemans in Pokémon Heart Gold and Soul Silver. According to Andriasang, the Pokémon Sunday TV show revealed a new pedometer device used in the game, called the "Poké Walker," that resembles a cross between a Pokeball and the Pokémon Mini handheld. For some reason, Nintendo decided to make another wireless pedometer peripheral for the DS rather than allowing people to use the existing one.
The device allows you to build one Pokémon's experience and personal affinity simply by walking. In addition, the Poké Walker generates "watts," which can be used to catch wild creatures and find tools inside the Poké Walker world to send back to the full game.
