How it loads the bar

Per side is (target − bar − collars) ÷ 2, loaded largest plate first, the way you would at the rack. That is not always the fewest plates, but it is the load every lifter recognizes.

If the weight can't be made with your plates, you get the nearest loads below and above. Tap either to use it. Competition collars weigh 2.5 kg each (about 5.5 lb); gym spring collars weigh so little they are ignored.

Defaults are a 45 lb bar with 45 / 25 / 10 / 5 / 2.5 plates, or a 20 kg bar with 25 / 20 / 15 / 10 / 5 / 2.5 / 1.25. Turn on 35s or 1.25s if your gym has them. Your choices are kept on this device.
