Troops on the go are always looking for compact and lightweight ways to get a workout. For those who find themselves in just such a situation, Rubberbanditz just might be worth taking a look at. The system uses rubber bands to provide resistance and was developed by company owner Ari Zandman-Zeman while serving in the Peace Corps. Rubberbanditz are easy to use and each kit comes with an instructional video. Additionally, they are not only lightweight but also are small enough to take a long on any trip.
