The coolest new fitness gadgets
Blast your playlist with these wireless headphones, sure. They also gauge heart rate with a sensor embedded in the right earbud. A voice coach tells you when you're sailing—or slacking. And a free app uses the phone's GPS to track runs. IriverOn, $200; IriverInc.com
Get in the fat-burning zone
The heart-rate watch has tiny lights under its face that pulse through your wrist to detect, yes, pulse—no chafey strap needed. Indicate what zone you want to sweat in, and it'll beep to alert you when you stray. MIO Alpha, $200; MioGlobal.com
Stay in touch
Leave your clunky smartphone at home. This Dick Tracy-style watch lets you use fitness apps (RunKeeper, MapMyRun) and take texts and calls, all from your wrist. Galaxy Gear, $299; Samsung.com
Strap on motivation
New for the FuelBand (besides cool neon pops): Bluetooth that automatically syncs stats to your smartphone. The tracker still monitors daily activity, converting movement to NikeFuel, their unique metric system you'll use to set, measure and achieve goals. Nike+ FuelBand SE, $149; Nike.com
Hire a "Coach"
This fancy touchscreen watch will be the boss of your run. Real-time audio cues and vibration alerts push you through the training plan of your choice (hill repeats, intervals, whatever). Plus, an MP3 player with 4GB of storage lets you pair it with wireless headphones. miCoach Smart Run, $400; Adidas.com/micoach
Train with a celeb
Kinect's HD infrared camera puts your silhouette next to A-list trainers (Jillian, Tracy, Shaun T!) and its sensors evaluate form, pace and even track your heart rate by monitoring fluctuations in your face, so you know how many calories you're burning. Xbox Fitness; Xbox.com/xboxfitness for price info.
Reach long-term goals
Loop this pod onto your sneaker laces. The relatively low-tech, wallet-friendly tool counts miles logged and uses Bluetooth to beam those numbers to a free app, so you can easily chart overall stats. You ran 62 miles this month? High five! $20; MilestonePod.com
Step on the souped-up scale for your weight, BMI and resting heart rate. And if you dare: Set it to automatically tweet or Facebook those stats from your smartphone. Smart Body Analyzer, $150; Withings.com
