Strength Standards & 1RM Calculators
If you train seriously, you should measure seriously. This page brings together the core FITTUX strength calculators so you can estimate your one-rep max, compare it properly to your bodyweight, and track real progress.
Absolute weight impresses people. Relative strength tells the truth. Use these tools to see where you actually stand.

Use a recent set performed with clean form. Treat the 1RM as an estimate, not a max-out challenge. Focus on your lift-to-bodyweight ratio and track the trend over time.
Strength standards aren’t verdicts. They’re orientation. The real goal is steady progress, balanced development, and staying healthy while the numbers climb.
