Gym slang, decoded
What PR, DOMS, natty, gains, and every other confusing gym term actually means.
Every gym has its own language, and if you're new, it can feel like everyone's speaking in code. "Bro, that's a new PR!" "Ugh, DOMS is killing me." "He's definitely not natty." If you've nodded along without actually knowing what any of that means — this glossary is for you.
The essential terms
PR
Personal Record. The most weight you've ever lifted for a given exercise, or the fastest/best you've ever performed something. "New PR on bench today" means you lifted more than ever before.
DOMS
Delayed Onset Muscle Soreness. The muscle pain that shows up 24–48 hours after a workout, not immediately after. That "why does walking down stairs hurt so much" feeling two days after leg day.
Natty
Natural. Someone who builds muscle without using steroids or other performance-enhancing drugs. "Is he natty?" is asking whether impressive muscle gains came from training alone or with pharmaceutical help.
Gains
Muscle growth or strength improvement. A general term for progress. "Chasing gains" means training with muscle growth as the primary goal.
Pump
The temporary muscle swelling that happens during a workout as blood rushes to the working muscle. It looks bigger in the moment but reduces within a few hours — not the same as permanent muscle growth.
Reps
Repetitions. How many times you perform an exercise in one set. "3 sets of 10 reps" means you do the movement 10 times, rest, repeat 3 times total.
Sets
A group of repetitions performed together before resting. If your plan says "3 sets," you complete the exercise's reps three separate times with rest between each.
Progressive overload
Gradually increasing weight, reps, or difficulty over time. This is the single most important principle in strength training — without it, your body has no reason to adapt or grow stronger.
Bulking
Eating in a calorie surplus to gain muscle mass, usually accompanied by heavy strength training. Some fat gain typically comes with it.
Cutting
Eating in a calorie deficit to lose body fat, typically while maintaining as much muscle as possible through continued strength training.
Spot / Spotting
Someone assisting you during a heavy lift to prevent injury if you fail the rep — common on bench press and squats. "Can you spot me?" is a normal, welcomed request at any gym.
Failure
The point where you physically cannot complete another rep with proper form. "Training to failure" means pushing a set until your muscles genuinely give out.
Deload
A planned week of reduced training intensity to allow your body to recover fully before resuming harder training. Not laziness — a legitimate part of long-term progress.
Skip day
Slang for missing a planned training session. Sometimes said jokingly to a gym-mate who's absent — "he took a skip day" — usually harmless but a good excuse to check in on them.
Streak
Consecutive days or sessions of consistent gym attendance. A concept that's become central to modern gym culture — visible streaks (like on Vega) turn consistency into something trackable and worth protecting.
