Clean System. Top quality produce, ABSOLUT odorless, which indeed is no longer taken for granted today! Modern design, not for anyone important, but I would like to mention it anyway. Minimal "working weight" - unless one works only with barbells - is 4.8kg, consisting of the bar to 1200gr and the two final weights 1800gr each, both of which are screwed. The remaining weights (4x1100gr and 4x1500gr) can be nice and clean stacked in any cupboard until you need them then. Perfect! The dumbbells are good in the hands, which then did not smell after work on cold metal, which I find very pleasant. For the little training in between highly recommended! For higher goals of course the way to the studio will not be spared ...
