Power benches with transport rollers

Transport rollers

— apparatus for strength exercises that create a load because the athlete must stretch an elastic cord or spring. In power benches and racks, expanders are usually made in pairs, for both hands at once. The range of exercises available with such apparatus is quite extensive. However, the disadvantage of expanders is that they cannot be adjusted according to the load. Therefore, as equipment for benches and racks, they are quite rare.
