Personal Trainer, in a Wristband?

Well, it sounds nice to have our own personal trainer. Most of us need the encouragement and advice to keep us in good physical shape. Unfortunately, most of us aren’t willing to pay the high fees they usually require. A Bluetooth company, known as Jawbone, has developed a different kind of personal trainer, though, one in the form of a rubber wristband . As reported by Economic Times , “Jawbone, the maker of sleek Bluetooth earpieces and colourful wireless portable speakers, now offers a product that monitors your activity and sleep, and, by confronting you with a visual record of your habits, inspires you to work harder. This isn't a new idea. The active ingredient is the same one found in gadgets like the Nike+iPod. If you conscientiously wear these devices, they work. The simple act of monitoring your own behavior inevitably encourages you — to climb more stairs, park farther away and bike instead of drive. WHY IT'S DIFFERENT The Up bracelet tries to improve on earlier devices in two important ways. First, its textured rubber exterior, available in a variety of colours and wrist sizes, is waterproof up to three feet. You can wear the band 24/7, even when you swim or take a shower. Second, the Up band uses an iPhone app as its brains and screen. Brilliant! You're already carrying around a computer with a colourful touch screen; why shouldn't it work with your glorified pedometer? THE INNER WORKINGS The band contains a metal spine; it's flexible but always returns to its closed oval shape when you let go. On one end, there's a clickable metal button and a couple of tiny indicator lights. On the other, a tiny removable cap conceals the Up's connector to your iPhone: a headphone jack. Yes, that's right: the Up band connects to your iPhone through its headphone jack. That's both its most ingenious idea and its most idiotic.” Do you think a rubber wristband could improve your health? Why or why not?
