1RM / Percentages

Known max

Percentage Calculator

Start from a max you already trust. The table rounds each share to a load you can put on the bar. It does not estimate the max. For that, use the one-rep max calculator.

Strength work often sits around 80–90% of the max. Muscle-building sets often sit around 65–80%. Those are ranges, not a program. Round to the plates you own, then lift that weight.

Questions

Does this page estimate a one-rep max?

No. Enter a max you already know. The table turns that number into 100% down to 50%.

What if the percentage does not match a plate?

Round to the plates you own. The precise line shows the unrounded weight.
