Strength Calculators

Estimate maxes, load the bar, compare lifters across bodyweights and plan sets by effort. Works in kilograms or pounds.

One-rep max by lift

One-rep max estimates set up for each lift, with training weights and the plates to load.

Which strength calculator do you need?

Kilograms or pounds

Every strength tool works in kg or lb, and your choice carries over between them. Points formulas are defined in kilograms, so pound entries are converted before scoring.

Estimates, not orders

Estimated maxes and RPE targets are starting points. How a set actually moves on the day matters more than the number on the screen. Use a spotter or safety bars for heavy work, and build up to new loads over several sessions.
