Tools built around transparent calculation

Bench Press Calculators is an independent, focused web resource for people who want quick bench press calculations without having to treat a result as a black box.

What we do

We build browser-based calculators for bench press 1RM estimation, percentages, plate loading, repetitions and common bench variations. Each tool is paired with an explanation of its inputs, formulas, assumptions and limitations.

Why we built it

Many calculator pages provide a number without enough context to reproduce or evaluate it. Our publishing approach is different: show the equation, show the assumptions, identify the sources and record when the calculation was reviewed.

What we do not claim

We do not claim that a formula can measure a person's exact maximal strength from a submaximal set. We also do not provide individualized medical or coaching advice.
