ABSTRACT:
A flexible barbell exercise apparatus which may be reconfigured to become rigid. Weight receiving vessels disposed at either end of a flexible tube may be filled with a weight bearing material in order to provide exercise weight resistance to a user. The weight receiving vessels may receive various types of weight bearing material, including sand. A rigid bar may be placed inside of a central bore of a flexible tube to stiffen the apparatus. In a rigid state, the apparatus may be used for conventional weight training exercises, such as bench or military press type exercises. The rigid bar may be removed to return the apparatus to a flexible state. In a flexible state, the apparatus may be used for aerobic conditioning, such as a bicycle peddling type exercise. The weights may be removed, and the tube folded in order to facilitate easy transportation and storage of the apparatus.
