Gym Terminology: A Beginner's Glossary (2026)

Walking into a gym for the first time, half the battle is the language. A trainer tells you to do "three sets of eight at RPE 7," someone asks if you're "using the rack," and the class timetable is a wall of acronyms. None of it is complicated once someone explains it plainly, which is what this page does. If you're still choosing where to start, a cheap ActiveSG gym session at about S$2.50 is a low-stakes place to practise the vocabulary in person.

Here are the terms you'll actually hear on a Singapore gym floor, grouped so you can skim to the ones you need. Learn the first handful and the rest of the room stops sounding like code.

The absolute basics

Rep. Short for repetition: one complete movement of an exercise, like lowering and pressing a dumbbell once. Everything else is counted in reps.

Set. A group of reps done back to back before you rest. "Three sets of ten" means ten reps, rest, ten more, rest, ten more. Beginners usually work in the two-to-four set range per exercise.

Rest. The pause between sets. Light, high-rep work needs 30 to 60 seconds; heavy strength work often needs two to three minutes for the muscle and nervous system to recover before the next set.

1RM (one-rep max). The heaviest weight you can lift for a single clean rep of an exercise. It's the standard way lifters measure strength, and most programmes prescribe your working weight as a percentage of it.

RPE. Rate of perceived exertion, a one-to-ten scale of how hard a set felt. RPE 7 means you had about three reps left in the tank; RPE 10 means you couldn't have done another. It's a simple way to auto-regulate effort on days you feel strong or flat.

PB or PR. Personal best or personal record: your heaviest lift or best performance on a given exercise. Hitting a PR is the everyday marker of progress most gym-goers chase.

Set structures you'll be told to do

Superset. Two exercises done back to back with no rest in between, then a rest. Pairing opposing muscles, like a push and a pull, is the common version and it saves time.

Drop set. Finishing a set to near-failure, then immediately stripping weight and repping again. It's a way to squeeze extra effort out of a muscle at the end of an exercise.

AMRAP. As many reps (or rounds) as possible in a set time or a single set. You'll see it in conditioning classes and at the end of strength sessions.

EMOM. Every minute on the minute: you start a fixed number of reps at the top of each minute and rest for whatever time is left. It's a neat way to keep intensity honest in a class.

Training styles on the timetable

Hypertrophy vs strength. Hypertrophy training aims to grow muscle size, usually with moderate weights and higher reps (roughly 8 to 15). Strength training aims to lift heavier, with lower reps (often 1 to 6) and longer rests. Most beginners get both from a sensible general programme.

Cardio vs resistance. Cardio (running, cycling, rowing) trains your heart and lungs; resistance training (weights, machines, bands) builds muscle and strength. A balanced week usually has some of each. A home walking pad or treadmill covers the cardio side on days you can't get to a gym.

HIIT and functional training. HIIT is high-intensity interval training: short bursts of hard effort with brief recoveries. Functional training uses whole-body movements meant to carry over to everyday life. Boutique studios build most of their classes around one or the other.

Mobility. Work that improves how well a joint moves through its full range, distinct from static stretching. Ten minutes of it before a session helps you hit better positions under load.

Programming and progress

Progressive overload. The core principle behind all progress: to keep adapting, you gradually add stress over time, usually more weight, more reps, or more sets. If your training never gets harder, your body has no reason to change. A pair of adjustable dumbbells makes this easy at home because you can nudge the weight up in small steps.

Volume. The total amount of work you do, commonly counted as sets times reps times weight, or just as hard sets per muscle per week. More volume drives more growth, up to the point you can recover from it.

Compound vs isolation. Compound exercises work several joints and muscles at once (squat, deadlift, bench press, row); isolation exercises target one (bicep curl, leg extension). Compounds give you the most return for your time, which is why programmes are built around them.

Split. How you divide your training across the week. A push-pull-legs split trains pushing muscles one day, pulling the next, and legs on a third; a full-body split hits everything each session. Beginners often do best on full-body two or three times a week.

Deload. A planned easy week with reduced weight or volume, taken every few weeks to let fatigue clear so you can push hard again. It feels like going backwards and isn't.

DOMS. Delayed-onset muscle soreness, the ache that shows up a day or two after a hard or unfamiliar session. It's normal, especially when you're new or trying something different, and it isn't a measure of how good the workout was.

Gym-floor and membership terms in Singapore

Free weights vs machines. Free weights are dumbbells, barbells and the plates you load onto them; machines guide the movement along a fixed path. Free weights build more coordination and let you train more naturally, while machines are easier to learn and often safer to push close to failure without a spotter.

Rack. The tall steel frame you squat or press inside, with adjustable safety bars. "Are you using the rack?" is the most common question you'll get asked on a busy floor. Sharing it between sets is normal etiquette.

Spotter. Someone who stands by to help if you can't finish a heavy rep, especially on the bench press. If you train alone, stay a rep or two away from failure on lifts that could pin you, or use a machine instead.

PT. Personal trainer, a coach you pay for one-to-one sessions and programming. Rates vary widely, and many people use a block of sessions to learn the basics, then train on their own.

Day pass. A one-off entry fee to use a gym without a membership, handy for trying a place before you commit. Chains like Anytime Fitness sell one for around S$20; a public ActiveSG gym charges roughly S$2.50 a session, the cheapest way to train pay-as-you-go.

24-hour and reciprocal access. Many chains run 24-hour keycard entry, and some, like Anytime Fitness (for instance the top-rated Havelock Outram branch), let one membership open every branch worldwide after an initial period. If you value training at odd hours or across locations, look for both. Our 24-hour gym directory lists the round-the-clock options by area.
