Taking the concept of fitness wearables up a few notches is the nifty AmpStrip from the creative folks over at FitLinxx. For those not so much into bulky watches or other mechanical toys of the like, this gizmo may be what you are looking for. After latching on to the left side of your torso, the tiny band-aid-esque device can remain in tact for up to one week on a single charge. The waterproof adhesive can help track key stats in the areas of vital heart rate, resting heart rate, recovery heart rate, steps taken, calories burned, and skin temperature in addition to a host of others. Compatible with iOS and Android devices via Bluetooth functionality, receiving all of this usefulness is an absolute cinch.
