FitLang is a human-readable markup language for defining workout programs and training sessions.
Design Philosophy: Human readability first, with lightweight markup that enhances rather than interrupts natural workout descriptions and being locked into traditional spreadsheet applications that can be too rigid and closed data formats to allow for sharing and interoperability.
This is just a simple example to show the language's flexibility. You can read the detailed language specification to learn more about all of its features.
Download or write a program file as a simple text file like basic-12-weeks.flp in any text editor.

...Currently this is all just a specification, but you can feel free to start using this as plain text files. Over time I hope to have FitLang-compatible mobile and web apps, but this shouldn't stop anyone from using this format to create/track/share training programs!
