The name Turkish Get Up is real. The movement comes from Ottoman army selection and training. I know one other way of their training as well. They were slapping mud. Heavy mud. There is a slap called Ottoman slap, which really very powerful and devastating. It is a slap that you put all your weight and arm and core behind and with an arc, you slap your opponent. When done by a novice, an easy move to evade, but I saw people who are experts on this in real life. They keep their arc very close to their body, and literally you can kimd of punch/ slap with your whole strength without breaking your own bones.
Another one again from Turkey, coming from Turkish traditional wrestlers. ( Turkish classic wrestling, is done by full body covered with olive oil, there was no points, no breaks, no time limit, some matches lasted the whole day, under hot Turkish sun) Tgos guys had to condition them selves to the bone. I know one move they were doing. Basically they were taking a huge stone from ground, kind of rack it, then throw with a push forward. They were doing this over and over, story says the whole day. Well no mention of their “program” but if whole day is true, then this means that they were following SF strength protocols
they could only do this whole day if they really take long rests in between. Probably there GTG for this move with seriously heavy singles.
