The Coolest Health and Fitness Gadgets at CES 2013

Last summer, fitness wristbands (ie the Nike Fuelband and Jawbone Up) hit the market and promised to change the way that we track our activity. Because they're taking off in a big way, we figured we'd see at least one or two newbies—if not a dozen—promoting bands that offer even greater benefit to your overall health. The first promising device we spotted was the Lark Life wristband ($150, lark.com), a 24/7 activity tracker monitors your movement, sleep hours, nutrition information, and mood by prompting you with questions throughout the day. In response, a coaching tool spits out tips. Did you spend all day cranking through a home improvement project? The device will probably tell you to take a hot shower and hit the sack early.
