The link between digital entertainment and exercise seems to be fairly well documented on the Wii alone, so it stands to reason that the combination would be fertile ground for other companies. And when's the last time you saw anyone on a cardio machine at the gym without an MP3 player?
Yamaha has clearly figured that out with its new "BodiBeat," a wearable gadget scheduled for August that it says is "the world's first music player/heart rate monitor that selects and plays songs to match the pace of the user's workout." It figures out which songs to play based on a "bpm" scale (beats per minute), which in turn determines the "runnability" of each tune to select one that's appropriate for the exercise.
That feature will be appreciated by anyone who's had "Feelings" come on while hitting peak strides on the treadmill. Though that's probably the least of their problems, if that's on the playlist to begin with.
