For FNGs, the swirl of inside-baseball lingo and jargon used at your average F3 workout can be a bit confusing. Like, for instance, What’s an FNG and why do people keep calling me that? (FNG stands for Friendly New Guy, or something along those lines… )

The F3 Lexicon is intended to help in that regard, providing a scattershot listing of lingo, sayings, expressions, acronyms, etc., that may come in handy when reading a BackBlast (A writeup of what happened on a workout) or attempting to decipher an email from a QIC (The leader of a given workout).

We also have a similar glossary for Exercises called the Exicon.


A brief review of what took place after an Event of some kind (workout, GrowRuck, etc.), particularly regarding leadership displayed by a Q during said event. An essential part of a good LDP. Typically comprised of 3 things that went well and 3 things that could use improvement, but could go much deeper as well. (abbr. AAR)
