Når du skal have vægtskiver på vægtstangen i styrketræning, så kan det sommetider godt blive lidt forvirrende, hvordan de skal fordeles.

Derfor har jeg lavet denne beregner. Den kræver naturligvis først og fremmest, at du ved [hvor meget vægt der skal på stangen](/hvor-meget-vaegt-paa-stangen/). Når du ved det, så gælder det om at få valgt de rigtige vægtskiver.
