摘要

The sports apparatus for body building comprises a spring component (1), preferably of rubber or expansive-elastic plastic and two cuffs (4,4') for fixture to arms or legs. The cuffs are fixed to the spring component at two points (3,3') spaced apart. The spring component in the area of the sleeves is enclosed by a protective casing (6,6'). The internal diameter (7) of the casing is slightly larger than the outer diameter (8) of the spring component in the non-expanded state.
