Load the bar with the plates you own Free
Pick your bar and the plates on your rack. Set a target, and the calculator draws the fewest plates per side. It is the plate math of the Block app.
The calculator needs JavaScript. On a 45 lb bar, 185 lb is 45 + 25 per side.
45 + 25 per side

Warm-ups to 185 lb
Few plates, big plates inside
The calculator loads the bar as you would: the fewest plates per side, the heaviest next to the collar.
- The fewest plates per sideOf all the ways to make the load, the calculator picks the one with the fewest plates. Big plates sit inside.
- Only loads your rack can makeYour lightest pair of plates sets the smallest jump. With 2.5 lb plates, loads go up 5 lb at a time.
- The closest loadsWhen a target is not possible, it shows the closest loads below and above it.
- Warm-ups in platesSteps at about 50, 70 and 90 percent, each at a load that needs few plates. Each step keeps the big plates on and changes the rest.
In the app, Today > Settings > Your gym holds your plates and bars. Every load you see is drawn with them, and the rulebook (Pro) only sets loads your gym can make.
In a session, your workout's warm-up sets come first, each drawn in your plates. Warm-ups are not judged.
Every set in your plates Free
Every set in a session is drawn in the plates you own, warm-ups included. Your workout lists its own warm-up sets, and the AI trainer (Pro, iOS 27) writes them by your rule.
Each lift also shows its next plate milestone: one plate a side, then two. Logging, warm-ups and your gym are free.
