Instant Plate Breakdown

Enter your target weight and see a color-coded diagram of exactly which plates go on each side. 45s are red, 25s are green, 10s are blue — confirm your setup from across the gym.

Your Actual Plates

Set how many of each plate your gym has. The calculator only suggests combinations you can actually load. If a weight isn't possible, it shows the nearest options.

💪

Every Bar Type

Olympic, women's, safety squat, trap bar, EZ curl — pick your bar and the math adjusts. Set a custom weight if yours is different.

Quick Adjust

Tap +5, +25, +45 (or kg equivalents) to nudge the weight without typing. Perfect for warm-up sets or on-the-fly changes.

🔖

Save Your Weights

Bookmark working sets with custom labels. "Bench Work Set — 225 lb" loads in one tap. No retyping. No remembering.

🌐
