Abstract: A soft shoulder weight device comprises an elongated weight bag having a first and second end which rests on the user's chest; the bag is formed from a flexible covering material sewn and shaped to fit across the shoulders and filled with ballast which migrates within the bag to accommodate the physiological make-up of the user. Another embodiment of the invention comprises two elongated weight bags, each of which rides on the shoulders of the user, one end of each bag resting on the chest of the user and the other end resting on the shoulder blades of the user. Each of the bags contains its own ballast, which migrates within the bag according to the physiological make-up of the user. The soft shoulder weight device is inherently self-padding, and additional features of the invention include pockets for the addition of solid weight elements, closures for providing access to the ballast material, and a liner used to provide additional security and complete containment of the ballast material.
