Every machine, rack, bag, and amenity you will meet in gyms around the world, explained in plain English. Every term below is also a filter in the GymMaps app: the community logs exactly what equipment each gym has, so you can search the map for a hack squat in Lisbon or a heavy bag in Bangkok before you ever leave home.
The long straight bar you load with weight plates. A full-size Olympic barbell weighs 20 kg (45 lb) and is the backbone of squats, deadlifts, bench press, and rows. If your programme is built around compound lifts, confirm a gym has real barbells before you visit: plenty of hotel gyms and small studios stop at dumbbells. You can filter gyms by this equipment in the GymMaps app.
Handheld free weights, usually racked in pairs from very light up to whatever the gym considers heavy. The number that matters for travellers is the top of the rack: budget and hotel gyms often stop at 20 to 24 kg, while serious gyms run to 50 kg or beyond. GymMaps gym pages list the equipment each gym actually has, so you can check before you show up.
A four-post steel cage (also called a power cage) you stand inside to squat, bench, and press. Its defining feature is adjustable safety bars or pins that catch the barbell if you fail a rep, which makes it the safest place to lift heavy without a spotter. This is the big one to search for as a traveller: a gym with a power rack can almost always support a full strength programme.
An open stand with hooks (J-cups) that hold a barbell at shoulder height so you can unrack it for squats. The difference from a power rack: a squat rack is open at the front and may have only short spotter arms or none at all, while a power rack is a full enclosed cage with safety bars. Both let you squat; the power rack just gives you more protection when training alone. Many gyms use the terms interchangeably, so check the photos on a gym’s GymMaps page if the distinction matters to you.
A barbell fixed inside vertical steel rails, so the bar can only move straight up and down along a guided path. Rotating your wrists hooks the bar onto the rails at any height, which makes it safe to train alone. It is not the same as a squat rack or power rack: those hold a free barbell, while a smith machine controls the bar path for you. Great for controlled pressing and accessory work, less ideal if your programme demands free-weight squats.
A reinforced section of rubber and wood flooring built to absorb dropped barbells. If you deadlift heavy or do Olympic lifts, a platform (plus bumper plates) means you can train properly without worrying about the floor or dirty looks from staff. Rare in hotel gyms, common in independent strength gyms: use the GymMaps map to find one wherever you land.
Solid rubber weight plates, all the same diameter regardless of weight, designed to be dropped from overhead without damaging the bar or floor. Essential for Olympic weightlifting and standard kit in CrossFit boxes. If a gym lists bumper plates, it is a strong signal the gym is drop-friendly and welcomes serious barbell training.
Two adjustable pulley towers facing each other with a walkway between them. Each cable can be set to any height, which makes it one of the most versatile machines in the gym: chest flyes, tricep pushdowns, face pulls, cable rows, woodchoppers, and more. When people ask “what is a cable crossover machine”, the answer is really: the machine that replaces a dozen others. A functional trainer is the compact, single-frame version of the same idea.
A seated cable station where you pull a wide bar down to your upper chest, training the lats and upper back. Think of it as an adjustable-weight pull-up: perfect if pull-ups are not yet in reach, or for high-volume back work after them. One of the most common machines in the world, so it is a safe bet in almost any commercial gym.
A machine where you push a weighted platform away with your feet, usually reclined at 45 degrees. It loads the quads and glutes hard while fully supporting your back, which makes it a favourite for high-volume leg training and for anyone working around a back issue. Almost universal in commercial gyms worldwide.
A machine squat performed with your back braced against an angled pad and shoulders under fixed shoulder pads, moving along a diagonal track. It hammers the quads with far less balance and spinal demand than a barbell squat. A staple of bodybuilding-focused gyms, and one of the machines with a genuine cult following: our post on legendary bodybuilding machines covers why lifters cross cities for a good one.
A plate-loaded squat machine that moves through a swinging arc rather than a straight line, keeping tension on the quads through a very deep range of motion. It is rarer than a hack squat and prized by bodybuilders, so gyms that own one tend to advertise it. If you spot it on a gym’s equipment list, that gym is probably serious.
A machine that loads the squat through a belt around your hips instead of a bar on your back. The result is heavy leg training with essentially zero spinal compression, which is why lifters managing back or shoulder issues seek it out. Still a specialty item: mostly found in dedicated strength and powerlifting gyms.
A seated machine where you bring two arm pads or handles together in front of your chest, isolating the pecs without any pressing. Also called a chest fly or butterfly machine. Most pec decks convert to a reverse fly for rear delts by flipping the seat or arms, making it two machines in one.
A seated pull where you draw a handle horizontally toward your torso, working the mid-back, lats, and biceps. Comes in cable form (low row) and chest-supported machine form, which braces your torso against a pad so the lower back does no work. One of the fundamental horizontal pulling movements, found nearly everywhere.
Short for glute-ham developer: a bench with ankle anchors and rounded hip pads used for glute-ham raises, hip extensions, and GHD sit-ups. It is one of the best pieces of kit for hamstrings and the posterior chain, but it is a specialty item you will mostly find in CrossFit boxes and strength gyms rather than commercial chains.
The motorised running belt everyone knows, with adjustable speed and incline. The useful detail when scouting a gym: how many it has and whether they allow sprint work. In hot climates a treadmill in an air-conditioned gym is often the difference between running and not running at all.
A stationary bike with a giant fan for resistance and moving arm levers, so the whole body works and the resistance scales infinitely with your effort. Also called an air bike or fan bike (Assault is the best-known brand). Beloved and feared for interval conditioning: ten hard seconds on one will explain the reputation.
The air-resistance rowing machine that is the de facto world standard: CrossFit workouts, indoor rowing competitions, and erg tests all assume a Concept2. If your training calls for rowing by split time or calories, a generic rower will not feel the same. GymMaps tracks equipment brands, so you can filter the map for gyms that have a genuine Concept2.
A vertical ergometer where you pull two handles downward from overhead, simulating the double-pole action of cross-country skiing. Made by Concept2, it delivers brutal conditioning while sparing the legs, which makes it popular for lifters on leg-day recovery and athletes with lower-body injuries.
A revolving staircase of real steps (often called a StairMaster or stepmill). It is low impact but genuinely hard work, and a favourite for steady-state cardio in bodybuilding circles because it loads the glutes and legs without pounding the joints the way running does.
A stationary bike with a heavy flywheel and aggressive road-bike geometry, built for standing climbs and sprint intervals. Different from the upright exercise bikes in most hotel gyms, which are geared for gentle seated cardio. Gyms with Peloton bikes get a connected version of the same idea, with on-screen classes.
Cast-iron balls with a handle on top. The offset weight makes them ideal for ballistic movements: swings, cleans, snatches, and loaded carries that build strength and conditioning at once. For travellers they are a great fallback, since a single pair of kettlebells can carry a full-body session when a gym is short on everything else.
Thick, heavy ropes anchored at one end that you whip in waves or slam for timed intervals. Zero skill requirement, near-zero injury risk, and a maximal heart-rate spike in under thirty seconds, which is why they appear in fitness gyms and fight gyms alike.
Weighted sleds you push (a prowler has upright poles to drive against) or drag with a harness across a turf strip. Sled work builds legs and lungs with no impact and almost no next-day soreness, since there is no lowering phase. If a gym lists a sled or prowler, it almost certainly has the turf lane to use it on.
A large freestanding steel structure combining pull-up bars, barbell stations, and anchor points for rings or bands, built so several people can train on it at once. The centrepiece of most CrossFit boxes and functional gyms. If you need a bar for pull-ups or somewhere to hang gymnastic rings, a gym with a rig has you covered.
Sturdy wooden or foam boxes in graduated heights (typically 50, 60, and 75 cm) used for box jumps, step-ups, and depth jumps. Foam versions are kinder to shins on missed jumps. A quiet signal that a gym takes conditioning and athletic work seriously rather than being machines-only.
The classic hanging punch bag, typically 30 to 60 kg, used to develop striking power in boxing, kickboxing, and Muay Thai. Variations matter: Muay Thai bags are longer so you can practise low kicks, uppercut bags are angled for punching up, and aqua bags are water-filled teardrops that are easier on the hands. A row of well-worn heavy bags is the quickest visual test of a real striking gym.
The small air-filled bag mounted under a rebound platform at head height, hit in rhythm to build hand speed, timing, and shoulder endurance. A boxing-gym staple. Its cousin the double-end bag, a small ball tethered to floor and ceiling, rebounds unpredictably and trains accuracy and head movement instead.
The raised, roped square where sparring and fight preparation happen. A gym with a full-size ring is signalling that it trains competitive fighters, not just fitness classes. If you are travelling to train, that matters: our gym travel guide covers how to pick a fight gym abroad and what drop-in sessions cost.
The fenced octagonal enclosure used in mixed martial arts. Training in a cage is not cosmetic: wall wrestling, cage clinch work, and getting up off the fence are skills you cannot rehearse on an open mat. Gyms with a cage typically run serious MMA programmes alongside their striking and grappling classes.
Open padded flooring for grappling: BJJ, judo, wrestling, and no-gi classes all live here. For grapplers scouting a gym, mat area is the single most important spec, since it caps how many people can roll safely at once. GymMaps lets you filter martial arts gyms by discipline and by facilities like mat space, padded walls, and grappling dummies.
A dry heated room, typically 70 to 100 °C, used after training for recovery and relaxation. Standard in Northern European gyms, a premium extra in most other places. Steam rooms are the humid, lower-temperature cousin. Every gym’s GymMaps page lists its amenities, so you know before you pack a towel.
A tub of cold water, usually 5 to 15 °C, for post-training immersion. Once a fighter-camp ritual, now increasingly common in high-end fitness gyms and recovery studios. If contrast therapy is part of your routine, filter for gyms that pair a plunge with a sauna.
Round-the-clock entry, usually via key fob or app, often with no staff overnight. For travellers this is gold: jet lag, red-eye arrivals, and shifted schedules stop mattering when the gym never closes. Note that some 24/7 chains restrict day passes, so check the gym’s access policy on its listing first.
A private mirrored room, ideally with harsh overhead lighting, where physique and bodybuilding competitors practise their posing routines. Rare outside dedicated bodybuilding gyms, and a sure sign a gym caters to competitors. If you are prepping for a show while travelling, this filter alone can pick your gym for you.
Knowing what a pendulum squat is only helps if you can find one. The GymMaps map shows community-verified equipment lists, day pass prices, and photos for gyms worldwide, and the filter guide explains how to narrow the map to exactly the kit, brands, and amenities you need.
