Abstract: Disclosed is a multi-purpose lat sling (61), which can be used to exercise and develop the latissimus dorsi, triceps, and abdominal muscles of the human body. It is comprised of a lat sling (42), having a connective band (25) separating a uniform pair of loops (26), a pair of U-shaped forearm belts (34), and a pair of assemblies, each comprised of an inner shell (50) and an outer skin (57). Sling (61) is attached via releasable surface means to a standard lat-bar, or typical pull-bar, and suspended therefrom. To exercise the latissimus dorsi, a user places each forearm through its respective loop (26). With forearm flexed, a portion of user's arm-elbow-forearm resides within shell (50) and skin (57) assembly. With both appendages thus encased, and resistance against the back of each upper arm, the user can then begin exercise by extending or adducting the arm.
