My legs still hurt. I'm finally catching up on sleep. Just a few days after leaving Las Vegas, CES still takes its toll on mind and body. But maybe if I had taken some time there to go for a run or actually monitor my sleep, I'd be feeling better? Well, it's a thought.

Reviewing our humongous video coverage of the show, I'm starting to feel guilty. I should be monitoring my fitness with some of the new technologies we saw -- or at least monitoring my sleep deprivation.

David Berlind, Fritz Nelson and I saw a ton of fitness technologies, running the gamut between devices that monitor your sleep (and even help you lucidly dream), monitoring your calorie intake to, well, monitoring other people. Like babies and elderly relatives. It's quite the mix. Here's a sampling, with videos to boot!

At CES, Nike and its partner TomTom announced the SportWatch GPS. I saw it just a few minutes after Nike announced this sleek device with runners like me in mind.

Sporting a simple interface and slim design, it connects up to Nike's network to help you track how much you've run and how far. It even has a guilt feature -- prodding you if you haven't run in a few days.

It'll cost between $299 and $399 when it comes out April 1. That's comparable to the price of other high-end sports watches with GPS capabilities on the market. It's good for cyclists, too.

Fritz checked out BodyMedia's FIT Armband. Rep Lauren Berg showed Fritz Nelson how, once strapped onto her left tricep, it collects thousands of data points every minute. This lets you take control of your fitness and weight management. "I can hold it my hand and see, hey, I've got two hundred calories to hit my goal, I'm going to hit the gym a little harder than I might have otherwise, " she told Fritz, explaining that the data the Armband monitors goes right to your smartphone for analysis.

Connection with the Android device and the iOS means you "can track your weight evolves," she added. To that, Fritz replied he hoped his weight would not evolve any time soon, and I think David and I are down with that, too. The cost: $199 starting price for the FIT Armband and a monthly subscript for the monitoring app ranging from $6.95 to $13.
