About FitBench

FitBench is a collection of free tools that run entirely in your browser. Fitness, nutrition and training calculators with the formulas shown.

Every tool shows the formula or rules it applies, includes worked examples, and is reviewed by a person before it is published. Nothing you type into a tool is uploaded: the calculations happen on your device.

The site is supported by advertising. Ads are clearly marked and never placed inside the tools themselves.

These calculators give general estimates from published formulas. They are not medical advice and do not account for your individual health; talk to a qualified professional before changing your diet or training.
