Fitness Acronyms List

Gym Fitness Acronyms

The world of fitness is a vast and sometimes confusing thing. There are many different variables and different ways of approaching things. That goes the same with the language used too.

There are many terms used in fitness, some more scientific than others but regardless most terms you hear in the gym are used often and because of that they are spoken in the form of acronyms or a short form using only the initials of each word rather than the whole phrase.

While this may make it a lot faster to explain certain workouts it would not make it any simpler in explaining them unless you understand said acronyms being used. 

To ensure you have some knowledge of fitness acronyms I have made a fitness acronym list which includes the 35 most common fitness acronyms used in and out of the gym including an exercise abbreviation list.

Following the acronym itself is a short simple description of each one.
