ELI5: Why are there so many great Eastern European Boxers, strongmen, and and mixed martial artists?
gpt
Different cultures place different emphasis on different sports. In Eastern Europe, the strongman/strongwoman sports are much more revered than they are in other places. As such, more people take those sports up as their childhood sport of choice, which means that there is a larger talent pool for elite athletes to emerge from. 

It's also worth noting that the startup costs for getting into these sports is very low. All you need is some padding, some gloves, and someone with a bit of training to show you the ropes, and you can *get started* at boxing. Compare that to, say, equestrian sports, which require a horse, full time lodging and care for the horse, and a host of other costs. A lot of Eastern Europe is poor compared to Western Europe and North America, so again, that funnels people into these sports.
