All too easy to generalize. I have seen a lot of gyms in every country where nobody deadlifts. 1,3 and 4 are things I have seen only in Italy though. Squat rack being used for towels was a new one on me and I not only have to ask one person, but many people to move.
Mirrors - Damn the mirrors get used a lot in comparison. Not saying the guys are not better looking than me, but the amount of between set posing and hair and outfit adjustment can be extreme.
Training is seasonal due to many gyms lacking AC. I see a lot of people arrive in the gym in February for the beach preparation and stop by the start of July. By then it is too hot and they are on the beach. Life's good and they are all happy.
Lazy, I would not call Italians lazy. Priorities are just different in the gym and this is also related to the heat in the summer months and lack of AC. You are forced to train hard on the big lifts for less time when the temperature approaches 40C. I have been deadlifting this morning and was feeling the heat on the warm-up sets!
What the general Italian gyms seems to lack (and so many gyms worldwide also have this issue) is good quality coaches/managers to help people maximize potential. Not sure how to cover this, but some mental toughness in the weight room. I see a lot of people working too far below their potential when their objective is the same as gym rats worldwide.
I have been trying the Olympic lifts and hope I will find a coach here to improve my technique.
It's not my current objective, but I know some excellent coaches here for boxing and Thai boxing.
With all that being said; Italy is a fantastic place for so many reasons (removing politics). The Italian diet is great, balanced and healthy. In general, I think Italians are one of the healthiest nationalities.
PS. This weekend I am hiking up to Monte Forato
