Barbell Plate Calculator, 1RM

You want 60 kg on the bar, so what goes on each side? This barbell calculator answers that instantly and draws the loaded bar, so you rack the right plates the first time instead of doing the math mid-warmup.

Type a target weight and it shows the plates per side, in kilos or pounds, with a warning when the number won't load evenly. From the same screen you can estimate your one-rep max from a set you actually did, and build a warmup ramp that climbs to your working weight in sensible steps, each with its own plate layout.

• A breakdown with a visual of the loaded bar
• A 1RM estimate that averages several standard formulas
• Auto warmup sets from an empty bar up to your working weight

It works offline with no account, which is what you want standing at the rack with no signal. Switch between kg and lb whenever you need to.

Made for anyone running a barbell program who's tired of counting plates and doing percentages by hand.
