Gym Rat
Tell a trainer your goals, name the exercises, count your sets — out loud, in Spanish.
Start with the words that change by country: push-ups are las flexiones in Argentina but las lagartijas — literally 'little lizards' — across Mexico. Squats are las sentadillas, pull-ups las dominadas. When a trainer asks about goals, the two answers that matter are bajar de peso (lose weight) and ganar músculo (gain muscle), and workouts are counted in series and repeticiones — always with numbers attached, like 3 series de 12 repeticiones. Nobody says el gimnasio mid-sentence anyway: it's el gym.
Below: the exercise, equipment and muscle-group words a workout actually uses, the slang locals throw around between sets — and a way to practice saying it all to a trainer out loud, not off a flashcard.
The warm-up pack
What gets said between sets — the trainer, the routine, and the honest self-talk.
01 · Crediting the person who built the plan
Mi profe me armó la rutina.
My trainer put together my routine.
Profe is the warm, everyday word for trainer in Argentina — entrenador personal is what's written on a business card, not what you call him.
02 · Saying you're headed there
Voy a darle al gym.
I'm heading to the gym.
Darle al gym is casual shorthand — ir al gimnasio is correct, but this is what it actually sounds like among friends.
03 · The coaching line you'll hear first
¡Estírate bien antes!
Stretch well before you start!
This is exactly how a trainer opens a session — direct, and said with an exclamation, not a suggestion.
04 · Naming which part you're training
Trabajo la espalda baja hoy.
I'm working my lower back today.
Espalda baja versus espalda alta is the distinction trainers actually use — knowing both means you can be specific about what hurts or what you're targeting.
05 · Choosing your machine
Voy a usar la bici fija.
I'm going to use the stationary bike.
Bici fija is the casual version — bicicleta estática is what's printed on the machine, not what people say.
06 · The gym-buddy request
Agarra unas mancuernitas.
Grab some dumbbells.
The diminutive -itas softens it into something a friend says, not an instructor barking an order.
07 · Talking numbers like a regular
Hoy hago 3 series de 12 repeticiones.
Today I'm doing 3 sets of 12 reps.
Stating the numbers plainly — series, then repeticiones — is what makes you sound like you know your own program, not like you're guessing.
08 · The honest post-workout line
Estoy mamado.
I'm wiped out / jacked. (Mexico slang — meaning shifts with tone)
Context does the work here — said with a laugh it means 'ripped', said flat it means 'exhausted'. Either way, it's exactly what a regular says, not a textbook phrase.
09 · Noticing your own progress
Me puse mamey.
I've gotten really built.
Mamey is Mexican gym slang for visibly muscular — it's playful self-praise, not a boast, so it's fine to say about yourself.
10 · The quick call to start
Hacer abdos.
Let's do some abs.
Abdos is the everyday shortening of abdominales — nobody says the full word between sets.
11 · The two-part goal, said plainly
Levantar pesas. Tirar grasa.
Lift weights. Burn fat.
Two short goals, stated back to back — this is how people actually talk about what they're there to do, not one long explanatory sentence.

Olivia
Your vocabulary teacher for this pack
No flashcards, no matching pairs — in the Gym Rat lessons you learn the words the way you'll use them: mid-conversation, slightly out of breath. Olivia sets up your first session with a personal trainer, and you describe your goals, your current routine and that old injury before the plan gets written. Then you're at the gym asking another member how a weight machine works, and planning the week with a friend — which muscle groups on which day, día de pecho, día de pierna. Every set, rep and body part said out loud until it's automatic.
Blank mid-sentence and nothing bad happens — she waits. That's the practice, without unnecessary judgement.

Quick answers
Las flexiones is the standard word — Argentines say flexiones de brazos or just flexiones — but in Mexico everyone says las lagartijas. In the Caribbean the anglicism wins for pull-ups: people say hacer pull-ups more than las dominadas.
State the goal first, then ask for the plan: bajar de peso (lose weight) or ganar músculo (gain muscle) — in Argentina, ganar masa or meter músculo. Note that in Argentina your trainer is often just el profe.
Sets are las series, reps are las repeticiones — gym-goers clip it to las reps. Always attach the numbers: 3 series de 12 repeticiones, 30 minutos de cardio. Vague volume is the mistake that gets you a shrug instead of a spot.
Weights are las pesas (levantar pesas = to lift). The treadmill is la cinta de correr — Argentines just say la cinta — the stationary bike is la bicicleta estática, colloquially la bici fija, and a dumbbell is la mancuerna.
It's el gym, not el gimnasio, and going is voy a darle al gym or me voy a entrenar. Routines get named by body part — día de pecho, día de pierna — and Mexican gym slang for jacked is estoy mamado. Use with care.
