The i-ShakeWeight app is an accelerometer powered workout device, which probably has little, to no, health benefits... BUT you'll sure look cool while doing it!!!!! Inspired by the sidesplitting show South Park, in which they parodied the actual Shake Weight. Make your friends laugh until they cry with this hilarious app, that encourages you while you workout your arms. You just shake it, up & down as i-ShakeWeight gives you extra encouragement as it cheers you on during your workout.
