How it works
We subtract the bar (and collars, if you use competition collars) from your target, halve it, and fill each side with the heaviest plates first. If your plates can't make the exact weight, we show the closest weight you can load.
A men's Olympic bar weighs 20 kg and a women's 15 kg under IWF rules; most US gym bars are labeled 45 lb. Source: International Weightlifting Federation, equipment.
