One embodiment of a massage device (1) constructed of plastic, foam, rubber, cork or similar material, which allows the user (8) to perform a hands-free deep tissue massage by rolling injured or painful muscles and connective tissue on a pair of symmetrically positioned tennis balls or any massage balls (10) of roughly similar size including golf, lacrosse, hockey, baseballs or softballs. The embodiments four tracks (2) permit the user to position one or more pairs of loose, freestanding round massage balls (10), so that a deep tissue massage may be performed on opposing sides of one or more body parts simultaneously. The tracks (2) also allow effortless ball changes to vary the size and hardness or to change the spacing between the balls for a highly individualized deep tissue massage particularly effective at relieving tender and painful connective tissue conditions including but not limited to back, foot, calf, chest, shoulder and arm ailments such as carpel tunnel syndrome and tendinitis. Other embodiments are described and shown.
