:o) I'm hungarian, but I train at a gym where you can find people all around the world. From Israel, Iraq, Egypt, Germany, Norway, China, Korea, Japan... etc, etc. Oh, and ofc, Hungarians and Gypsies.
So a little recap:
Japanese have work etique. They are quiet, polite, work hard (no wonder at the med-denistry-pharmacist courses they kick ass with their knowledge) but most of them has incredibly hard time packing on muscle. I've seen quite muscular and cut guys with japanese background, they surely work hard. Both genders included.
Other asian country's members are the opposite. I admit, they're usually perform well at school, and lot of them go to the gym. But, they don't get results. Lot of them are skinnyfat or chubby, they waste time with light machine training and cardio. And heck, they just maintain their appearance.
I generally like asians, they are always very polite, quiet, and you can always work with them on a station when you ask them, though lot of them has quite queer English accent.
Israelis are a diverse group. I've only seen 2-3 of them in the gym. They were skinny to the bone, their elbows or wrists were 2-3 times thicker than their arms-forearms, but they were banging out pullups of 15-20 reps with little rest and with full ROM (from deadstart to sternum 2 bar) and were strong in squats and presses. So great physical shape and strength, but nonetheless, skinny. They're very proud of being Israelis, most of them train in T-shirts with their nation's flag.
Guys from arabian countries: nah, I had bad experience with them in the gym. Surely, they're friendly and chatty, but they have more hair on their chests and armpits than an average wookie. Lot of them just carry their university notes into the gym to "study" between two sets of tricep pushdowns or on the stationary bike. Arabian girls also found, 99% of the time on cardio machines. Most of the guys-gals from this ethnicity has trouble with loosing fat, heck, I've never seen any of them in the gym who were not fat. (Those who are thin are always outside the gym...) Oh, and I hate their clothing. Lot of them train without shoes in socks with huge holes, old jumpers with nasty stains, etc, etc.
Africans: HUGE. Big, strong. Lot of them has wunderbar genetics. Oh, lot of them hasn't. But they are generally quiet and reserved, train solitary.
Germans: Most of the advanced guys who look and lift decent are among them. They are certainly hard working, and actually in love with free weights. They dn't afraid to ask for equipement, always wipe their sweat, even ask for spotting. So, generally, they're just regular hard working folk with calm personality.
Icelandic, Norwegian, Danish: Old clothes, worn shoes, trouble with keeping equipement clean, but at least they speak great English, lift weights and don't do weird stuff. Few of them are familiar with the site, so they know how to lift, and I've seen a weightlifter among them 2. BTN jerks with snatch grip, snatches, oly-squats. Guy was explosive-strong. Complimented my squats and even mentioned Thibs.
Please, keep in mind: these examples are STUDENTS. They're mostly from med-dent-pharm. schools, or engineers. So my examples are not representative for the nations- just for their students.
And now, natives:
Hungarians: diverse. At the town of the university, they tend to be polite, hard working folk. Wipe of sweat, train in adequate clothes. There are some gym-monkeys who do quite weird stuff, but who cares? They're usually office workers at the age of 35-40 without any clue how to train, so it isn't special, I'm sure most of the guys are familiar with their choices of excersises (sternal bounce-presses, pec-dec, horizontal lat pulldowns with momentum, concentrated curls..) Girls in that town are great! Great in shape, they train hard, mostly shoulders-lats-biceps and lower body ofc. But they don't do idiotic excersises. They stick to basics: squats-deads-chinups (assisted), shoulder presses, step-ups, lunges. Their bicep training is ridiculous (/sarcasm: they train it hard!): Most of them are doing cable curls-preacher machine curls-incline db curls with good form. Supersets with triceps (for that: 2 forms of pushdowns (rope-v-bar), dip machine.
I like the back training of girls too. Just like a guy would do them: chins-pulldowns-rows. I won't go into the details of their lower body training, but that is generally great too. Well, they're in great shape, round shoulders, toned arms, round asses, nice thighs, slight V-taper.
Quite the contrast: girls in this town (where my family lives): cardio bunnies. They walk 15-20 mins on treadmill, then do a few sets of abs, adductions-abductions and call it a day. Never seen any of them train seriously. Most of them are obese or skinny, without shape. So the contrast is soo sharp between the two towns (only 90kms from each...) that it hurts. Hard training and work etique there, obesity, half assed efforts and no clue what to do here.
I won't write any further, not from gypsies. Those folks deserve a novel, yet, after years they can still provide surprises.
