Load the right plates for your target weight
See exactly which plates go on each side of your barbell, plus an auto-generated warm-up ladder.
Setting up a barbell with the correct weight takes time and mental math. Plate Loader solves this by letting you enter a target weight and telling you exactly which plates to load per side. Choose your bar weight, select the plates you own, and the app displays a color-coded barbell diagram showing the correct loading, plus tells you if you hit the target exactly or how close you get.
What it does
You pick a unit (kilograms or pounds), choose your barbell weight, select which plate denominations you own, and enter a target weight. The app calculates the greedy solution—loading the heaviest plates first—and shows you a visual barbell with color-coded plates on each side. Below that, it lists the plates per side in a readable format. It also generates a warm-up ladder with six steps from 40% to 100% of your target, telling you the plate configuration for each step and how many reps to perform.
