Weight lifted for submax reps (usually ≤10)—estimated one-rep max for programming (not medical).
This page uses the Epley estimate 1RM = weight × (1 + reps ÷ 30) with reps between 1 and 30 and a positive weight. The result is shown in the same mass unit you typed; it is an estimate, not a competition lift planner.
Reps must be 1–30; the Epley formula is an estimate, not a competition program.
