A device for use by a person for dynamically exercising muscles comprising: an elongated substantially cylidrically shaped flexible enclosure which decreases in diameter in all radial directions toward each end to a point, each end of said enclosure being pleated into a closed condition by being folded over onto itself many times with the folds being in substantial alignment with the axis of the enclosure; first and second flexible holding strap means operable to be held by said person in his left and right hands, respectively, said strap means including end portions which fit around the pleated ends of said enclosure; first and second connecting means securing the ends of said first and second strap holding means, respectively, around the opposite pleated ends of said flexible enclosure, and a liquid only partially filling said flexible enclosure whereby said flexible enclosure can easily bend and wherein movement of said person\s hands holding said holding means causes said liquid to move within said flexible enclosure resulting in dynamically exercising said person\s muscles.
