Fitness Dictionary

Gym culture has a lot of words people throw around like everyone should already know them. This page is the cheat sheet, minus the weird gatekeeping.

B

Bro

Gym culture
What people mean

The name of my dog.

Why it's herefoundbro.com
C

Circuit

In the app

A group of exercises you run through in order, then repeat.

What people mean

Do exercise A, then B, then C, rest a bit, and go again. That is a circuit.

In JustGains

This one is built into JustGains. If a workout uses a circuit, the app groups it for you.

Creatine

Gym culture

The supplement almost every fitness conversation eventually reaches.

What people mean

Creatine helps with short, hard efforts and is one of the most researched supplements in sports nutrition. Less magic powder, more very boring science that happens to work.

Why it's here

Good term to know, just not something JustGains tracks right now.

D

Dry Scoop

Gym culture

Taking pre-workout powder dry like the laws of common sense do not apply.

What people mean

Dry scooping means swallowing pre-workout powder without mixing it first. It became internet gym theater because it looks hardcore for about three seconds and chaotic for the rest of the story.

Why it's here

Not a JustGains thing, but absolutely a fun phrase. The behavior itself? Not recommended 🥲

G

Gains

In the app

Usually progress. In JustGains, it means a little more than that.

What people mean

In normal gym talk, gains usually means muscle, strength, progress, or any sign your hard work is paying off.

In JustGains

Inside JustGains, Gains can mean the high fives people give on posts, and it also refers to creator impact: how many users did workouts you made, including workouts people made from yours further down the chain.

Giant Set

Gym culture

A superset, but with even more chaos.

What people mean

A giant set usually means three or more exercises done back-to-back before you rest.

Why it's here

Not a separate JustGains label right now. We think superset is perfectly self explanatory.

Gym Baddie

Gym culture

A gym-culture term for someone who trains with style and confidence.

What people mean

Usually it means someone who looks put together, trains consistently, and brings main-character energy to the gym.

Why it's here

Core feature of JustGains since the day you joined ;)

H

Hypertrophy

In the app

The fancy word for training to build muscle.

What people mean

Hypertrophy means muscle growth. Usually that means enough hard sets, enough recovery, and repeating it long enough for your shirts to notice.

In JustGains

We offer programs for hypertrophy, but you can also train for it with prompts, logging, and progression.

I

Interval

In the app

Work, rest, repeat.

What people mean

Intervals break training into timed chunks like 30 seconds on, 30 seconds off. Great for cardio, conditioning, and anything that gets spicy fast.

In JustGains

Also built into JustGains. You may see interval-style groups when time matters more than reps.

M

Macros

Gym culture

Protein, carbs, and fats.

What people mean

These are the three main nutrients that make up your calories. If someone says they are tracking macros, they usually mean they are watching how much protein, carbs, and fat they eat.

Why it's here

Not tracked in JustGains right now. We do plan on launching a macro focused eatery - "Wholly Macros" one day

P

Periodization

Partly in the app

Cycling your training in planned phases.

What people mean

Periodization means organizing your training into blocks or phases that each focus on something different, like building strength, then volume, then peaking. The idea is that you cannot push everything at once forever, so you rotate the emphasis.

In JustGains

JustGains supports building programs with multiple phases. You can structure mesocycles and progression blocks to follow a periodized approach.

Progressive Overload

Partly in the app

Doing a little more over time.

What people mean

That could mean more weight, more reps, more sets, better control, or harder variations. The point is giving your body a reason to adapt.

In JustGains

This idea is all over JustGains. The app helps you log workouts and track progression.

Pump

Gym culture

That full, tight feeling after a good set.

What people mean

A pump happens when blood and fluid rush into the muscles you are training, making them feel fuller and look more pronounced. Temporary, yes. Satisfying, also yes.

Why it's here

JustGains does not track pump as a metric. But if someone says they are chasing a pump, now you know what they mean.

Pump Cover

Gym culture

The oversized shirt or hoodie people wear before the mirror starts being rewarding.

What people mean

A pump cover is a loose top worn at the start of a workout. Some people wear it to stay warm, feel comfortable, or save the reveal until the pump shows up.

Why it's here

Not a JustGains feature. Pure gym culture, heavily supported by oversized tees and confidence. Imagine our exercise models with some sponsored outfits tho @nike 😏😏

R

Reps

In the app

How many times you do the movement.

What people mean

If you squat 8 times, that is 8 reps. Nice and simple.

In JustGains

Reps are tracked directly in JustGains and show up throughout workout logging and stats.

RIR

Partly in the app

How many good reps you had left in the tank.

What people mean

2 RIR means you probably could have done about two more solid reps before failure.

In JustGains

JustGains has some RIR-related profile data, but it is not a front-and-center logging field the way RPE is.

RPE

In the app

A 1 to 10 rating for how hard a set felt.

What people mean

The higher the number, the closer you were to your limit. It is basically a quick way to rate effort without writing a novel about your suffering.

In JustGains

This one does show up in JustGains. RPE can be part of the set data and appears as its own measurement when a workout uses it.

S

Sets

In the app

A chunk of reps before you rest.

What people mean

Three sets of 10 means 10 reps, rest, then repeat until you have done that three times.

In JustGains

Sets are one of the main things JustGains tracks. Add them, complete them, and use them to log the workout properly.

Split

Partly in the app

How you break your training across the week.

What people mean

A split is just the layout of your training days. Think Push/Pull/Legs, Upper/Lower, or Full Body.

In JustGains

You will see split-style choices in JustGains prompts and workout generation. We use the idea, even if there is not a giant split button anywhere.

Superset

In the app

Two exercises back-to-back with little or no rest.

What people mean

Finish one exercise, move straight into the next, then rest. Classic time-saver, classic humbler.

In JustGains

Built into JustGains as a workout group, so supersets show up clearly together.
