Exercise One-Rep Max Calculator
Pick the exercise, then enter the load and clean reps from a hard set. The result estimates a one-rep max for that exercise only: a 100 kg squat does not imply a 100 kg bench, and a machine result does not transfer to a barbell.
Use a hard set of 1–12 clean reps. High-rep or all-out sets produce shakier estimates; do not compare unrelated exercises.
What do you do with it?
This is a useful starting point, not a new program. Keep the exercise, technique, effort, and recent training in view before you change a working weight.
