About

trainphysique.com is made by Definite Labs, Inc., the company behind Physique, an iPhone app for people who want to build muscle, get stronger and keep showing up for their training.

The calculators here are free and will stay free. They turn published program rules into working weights, with worked examples and the rounding conventions explained on each page.

How we write the guides

Guides are published under Definite Labs, Inc.. We identify the program edition or source, explain what each calculator includes, and separate examples from instructions. The website covers some programs that are not in the app; the app library lists the built-in options.

We make Physique to give lifters a clear next workout and a visible record of their effort. The free guides help you choose a plan; the calculators get your session ready; the app brings guided workouts, set logging and progress tracking together.

Sources and corrections

Program rules come from the creators' own books, posts and spreadsheets, cited on each page. If a number here is wrong, say so through Physique supportand it will be fixed.
