StrongCalc is a set of free fitness calculators. The aim is simple: give you a clear number, tell you which formula produced it, and be honest about how accurate it is.
How the calculators are built
Each calculator uses a formula that is published and widely used, such as the Mifflin-St Jeor equation for calories, the US Navy method for body fat and the Epley formula for one rep max. The formula is written out on every page so you can check the result yourself.
What the results are for
The numbers are estimates for healthy adults. They are meant to help you plan training and eating, and they do not replace advice from a doctor, dietitian or qualified coach. If you have a medical condition, are pregnant, or are under 18, talk to a professional before changing your diet or training.
