That's very true I always wanted to ask why are those groups so good those fighting physical sports I don't think any other group is better. Is it in the culture or what?
Well they’re good at wrestling first and foremost. Their UFC fighters have wrestling foundation, they aren’t as good of strikers. I would say they are successful due to 3 main reasons
1. Body type: They have a perfect body type for wrestling. Short limbs, long torso, low center of gravity and their short arma put on muscle very well. As a result they can explode and attack opponents with long arms/legs pretty well
2. Culture. They always had a good tradition of wrestling and they have lots of good coaches of wrestling from the Soviet Union era. Same with Kazakhstan except with striking we produce boxers and kickers not really wrestlers.
3. Diet. Many of these guys grow up in the Caucasus mountains on natural food and lots of protein.
