A multiple use exercise device is formed as a closable hollow container which may be filled with a ballast substance, such as water, by the end user. The hollow container is penetrated at each end by a recess. The central portion of each recess is spanned by a handle, giving the device utility as a barbell. A central cutout, shaped to accomodate the trunk of the user, enhances this utility by making the container easier for the user to hold close to the body, and by increasing the range of motion possible at full extension and contraction, during exercises normally performed with a barbell. A flat surface, located on the side of the container opposite the central cutout, serves as a stepping surface for the performance of stair stepping type exercises. A pair of voids, penetrating the container from the central cutout to the flat stepping surface, are shaped to accept the insertion of the user's feet from either the top or the bottom. When the feet are inserted from the bottom, the device exerts a downward force on them, facilitating the performance of situps or leg extensions. When the feet are inserted from the top, they are elevated and anchored as a fulcrum for the enhanced performance of pushups. The device facilitates or enhances the performance of curls, presses, rows, squats, arm extensions and most other exercises possible with a barbell, as well as pushups, situps, leg extensions and stair stepping type exercises.
