The Philips Activa has got you covered. This teensy gadget is an MP3 player, pedometer, trainer, and calorie counter. Whoa, that's a mouthful.

Instead of trying to juggle your favorite musical device and a pedometer while exercising, the Philips Activa has put the two together to create the ultimate electronic hybrid workout friend. Since the smart tool digitally monitors your running progress in terms of distance, speed and calories, you've got no excuses now.

Implications - Exercise can be an incredibly dull and trying undertaking, so companies willing to inject some levity into the process will be rewarded by the tens of millions of consumers trying to make work-out sessions more bearable. Adding a level of functionality on top of the entertainment means that the product will inevitably attract even more customers weary of boring, extended regiments.
