You're fat, lazy, and not getting enough sleep. At least that's what the consumer electronics industry seems to be saying with the recent deluge of fitness devices announced. In the last month alone, we've seen the introduction of the seventh generation iPod nano with integrated Nike+ sensor, the Fitbit Ultra clip-on sensor, and Motorola's MOTOACTV knockoff of the iPod nano + LunaTik watchband. And that's not even counting the myriad of dedicated cycling, running, and swimming computers targeting hardcore athletes over the same period.

See, fact of the matter is, we are fat, lazy, and tired, particularly in the US and increasingly in parts of the UK and Western Europe. According to 2008 statistics compiled by the US Department of Health Service, 68 percent of US adults are overweight or obese. Ironically, the US also leads the world in gym memberships with 50.2 million people (16.3 percent of the total population) toiling away in air conditioned sweat boxes. Unfortunately, 80 percent of those well meaning individuals don't actually use their memberships beyond the month of January — "resolution month" — resulting in about $12 billion wasted each year. In other words, the recent glut of fitness products has nothing at all to do with corporate altruism; there's gold in them thar cellulite hills!

Today also marks the retail release of yet another fitness device: Up, by Jawbone. While most of you know the Jawbone brand from its highly stylized Bluetooth earpieces, the company has branched out recently with its well-received Jambox portable speaker. The Up fitness wristband is meant to be worn 24-hours per day, every day. Like the Fitbit, Up includes an accelerometer that tracks your movement in order to give an estimate of your calories burned. It also features a sleep measurement mode that continuously measures your sleep cycle. However, unlike the Fitbit, Up can vibrate your wrist at just the right moment so that you awake feeling refreshed and ready to start the day. Or at least that's the claim. Up is also very much post-PC, meaning it connects directly to the iPhone's headphone jack to synch with a free app. Question is: is it worth $99 given all the competition?
