Here’s an MP3 player that will help you get fit. The fitness-friendly W1, also known as MyFit, is the first portable player that includes built-in fat and stress sensors. An accelerometer lets you measure calories burned while walking or running. The MyFit also includes functions for recording meals and exercise. In addition, there are tools to help quit smoking and improve hydration. Since it’s an MP3 player, you can create exercise playlists that can be controlled with a single tap. A video player and FM radio tuner are also included.

The MyFit will be available sometime in Spring 2010.  See more pictures on ZDNet.
