Top fitness gadgets to make exercise easier

Nike Plus

This small device lets you listen to music while it tracks your exercise progress on an iPod nano by unobtrusively fitting the waterproof and virtually unbreakable sensor into your sock liner. The iPod nano will give you feedback on distance, time, pace and calories burned and after your run, a performance summary appears on the iPod nano screen and it can also be heard through the headphones.
