Strength Percentage Calculator

How to use Strength Percentage Calculator

A strength percentage calculator converts a one-rep max into training loads such as 60%, 70%, 80%, or 90% of max.

Basic idea

One-rep max x percentage = target training weight

Should percentages be based on true 1RM or training max?

Many programs use a training max slightly below true 1RM to keep workloads manageable.
