Weighted adjustable fitness device

Abstract

A weighted adjustable fitness device is disclosed. The device includes a tubular body constructed of a material of a generally rectangular shape. Two edges of the tubular body attached together to form an interior volume. The length of the tubular body is at least an order of magnitude larger than the diameter of the tubular body. The device further includes a reinforcement border attached to or adjacent to the two attached edges of the tubular body. The device may further include a collapsible inlet which is in open communication with the interior volume and which is movable from a first position in which it extends at least partially outward from the tubular body, to a second position in which it extends at least partially inward into the interior volume. The device may further include an end closure.
