The Yahama BodiBeat quite literally plays tunes to match the tempo of your walk or run. Synchronization is accomplished through the built-in accelerometer. It also doubles as a heart monitor (clips to your ear), which enables the BodiBeat to adjust the music and workout to achieve 70% of max heart rate when in ‘fitness mode’. If you’re of the serious runner ilk, then you’ll enjoy ‘training mode’, which measures and tracks your workouts. Battery will last 9 hours, and holds about 100 songs (512mb of storage…I think).
