'BLACK LINE' is a sling well-suited for exercising in a hall, gym, outdoors, or practically anywhere. It is made to withstand extensive use, and has details such as buckles to adjust the length for measuring progress, good hand grips with leather fittings.
The hand grips can be adjusted so as to make a “hip sling”, a “neck sling” and a good basis for the foot when doing exercises with the feet. It comes with two screws for fasting to the celling and user manual together with an exercise poster.
