Seen At 11: New Fitness Gadgets Let You Track Your Health

NEW YORK (CBS 2) -- Remember those pedometers? Now, high-tech gadgets do much more than just count steps. They can track your every move, even while you sleep.

Whether you're trying to lose weight, move more, or train harder, there's a fitness gadget for you.

"It's about your entire day, so when you have this device it's gonna encourage you to make small changes throughout the day and those changes really add up," certified personal trainer Jaclyn Emerick told CBS 2's Kristine Johnson recently.

Emerick said personal activity devices are for everyone. Worn on the arm, wrist, or clipped to a waist band, the trackers have sensors that measure movement.

"They track the calories you burn; the minutes you're active during the day. Your distance, your pace, stairs you climb, hills you walk up," Emerick said.

And unlike pedometers, they do much more than measure steps.

"A lot of them will use a 3D motion sensor and accelerometer and an altimeter that will track 360-degree movement, not just moving forward and backward," Emerick said.

Personal trainer Sam Cardona said it's easy to track your progress because these devices sync to computers and smart phones.

"I think using your phone is the easiest way you, it's so natural. Everyone's always looking at it, always checking their e-mail, so to use it to monitor your fitness is just a logical progression," Cardona said.

Johnson saw sneakers that use technology to measure how high you step or jump.

Some of the new devices will track you 24-7, even while you sleep.

"It's gonna tell you how long it took you to fall asleep, how many times you woke up at night and the quality of sleep that you get," Emerick said.

You can program a personal goal with a certain band. The display changes color when you achieve it.

"It made me want to just get up and walk more. I found at the end of the day if I wasn't near that goal that I had set for myself I would try to exert a little more energy to get to that final goal," Lindsey Benoit said.

Another device plays music and also reads your texts, tweets and Facebook messages out loud.

"You'll hear it through the ear phones. You won't be able to respond, but you'll hear those," Emerick said.

One gadget isn't enough for J Travis. He was using three to train for a 120-mile charity bike ride.

"We have to bike on average between 12 to 15 mph and for me, who is just kind of coming from zero, it's very hard for me to keep up," Travis said.

And the message he's getting?

"It is definitely telling me to work harder, much like my coach is," Travis said.

Some of the devices have a diet component that let you precisely log your food and water intake.
