The One Rep Max vs Load That Bar

The One Rep Max calculator uses a little previous knowledge to give you an approximation of what amount of weight you could lift one time. Use this value to push yourself while remaining safe, and chart your progress along the way.

Load That Bar helps lifters quickly determine exactly what plates to load on each side of a barbell. Enter your target weight, choose your barbell type, and the app calculates a clear per-side loading guide with a visual plate layout. You can switch between pounds and kilograms, customize available plate sizes, and use Ladder Mode for multi-set progression planning. Version 1.1 is a top-to-bottom rebuild of how the app looks and feels, plus real new features: • Home Screen widget and Siri Shortcuts — see what to load without opening the app • Workout history — every set you calculate or log is saved, grouped by day • Multiple named gym profiles — switch between your home rack and the gym in one tap • A real light mode, full Dynamic Type, and VoiceOver support throughout • A proper iPad layout and a guided setup that actually asks about your plates Load That Bar is fast, simple, and built for practical gym use without accounts, subscriptions, or required setup.
