LiftLogic: Barbell Calculator

LiftLogic — Barbell Plate Calculator Type your target weight. See exactly which plates go on each side — instantly, with a live barbell graphic that updates as you type. Whether you're powerlifting, weightlifting, or just trying to hit a new bench press PR, there's no more chalk-dust math between sets.
