Gym Lingo Explained: Unlock Fitness Terms for Success

Bodydisciple's A Beginner’s Guide to Gym Lingo

Starting the gym is intimidating enough without feeling like you’ve accidentally walked into an episode of Love Island: Protein Edition.

People are tossing around phrases like “in prep” or “hitting a PB” while you’re just trying to figure out how to adjust the seat on the leg press. Relax — you’re not alone.

Here’s a friendly, no-judgement guide to some of the most common gym slang you’ll hear, so next time you overhear a conversation in the free weights area, you’ll actually know what’s going on.


Gym Lingo Cheat Sheet


In Prep

Translation: “I’m on a strict diet and training plan because I’m getting ready for a bodybuilding show or photoshoot.”

Expect mood swings, tupperware meals, and a slight obsession with rice cakes.


PB / PR

Translation: “Personal Best” (UK) / “Personal Record” (US). The heaviest you’ve ever lifted or the fastest you’ve ever run.

Example: “Smashed a PB on deadlifts today!” = Look at me go.


Macros

Short for macronutrients: protein, carbs, and fat. Tracking your macros means counting these daily like a maths-obsessed bodybuilder.

Warning: Macros chat can get very serious.


Natty

Translation: Natural. Someone who trains without performance-enhancing drugs.

Often accompanied by the phrase: “All natty, mate.” (Always said unprompted.)


Bulking / Cutting

Bulking = Eating a surplus of calories to gain muscle.

Cutting = Eating in a calorie deficit to lose fat.

Sometimes happening within the same month after panic-checking holiday photos.


Bro Split

Training style where each gym session focuses on one muscle group. Usually sounds like:

Chest Day

Back Day

Leg Day (…and often skipped day.)


DOMS

Delayed Onset Muscle Soreness. That glorious (and slightly awful) ache that kicks in 24-48 hours after training. Walking downstairs post-leg day? Good luck.


Superset

Two exercises back-to-back with no rest in between.

Translation: Hurts more. Works faster. Looks cooler.


Mind-Muscle Connection

The art of really feeling the muscle work during an exercise.

(Not to be confused with simply grimacing at yourself in the mirror.)


Gym Fail

A moment of tragic comedy — dropping a dumbbell, missing a box jump, or forgetting to clip your barbell properly. If it happens near someone with a camera… congratulations, you’re viral now.


Final Thoughts

The world of gym lingo might sound ridiculous at first, but soon enough you’ll catch yourself saying things like “Hit a cheeky PB today, feeling natty strong” without even blinking.

Until then, remember: nobody knows everything when they start — just focus on showing up, moving your body, and maybe learning a phrase or two along the way.

And if all else fails, nod, smile, and say “Bro, that’s sick.”

Works every time.
