This thing with martial arts science is really strange to me, there is no fight sceince, and joe rogan is full of it. Half of what he says on the ufc is not true. Whenever someone is in a head lock he wants to say the wrist is not deep, his hips are this way or that way, he's just wrog half the time, he is a guy who is eager to sound like an expert, and in this eagerness he allows himself to say things he knows are bullshit but he knows people will trust him.
I've taken tkd, tkd is a martial art not a sport, an ART. The kicks are emphasized but they are no tmeant to be effective, people do not compete by hurting themselves with kicks in tkd, it is not a sport. Muay Thai on the other hand is a sport, the kicks are ment to chop people down, it is not a martial art it is a sport, that's what makes it fucking effective.
Joe Rogan is a pot head bullshitter, his podcast is unlistenable, he talks about how aliens built the pyramids with a serious face,
I also want to say that MMA is in a seriously awful state, people are good at wrestling and bjj but most people in the UFC can not throw a punch correctly. These winding looping hooks are no good, they're not a different but equal style, they are simply inferior, which is why guys who simply throw tight hooks, quick straight crosses, and check leg kicks instead of just eating them and hoping to get a take down dominate so hard. I don't know who is training all these fighters, but they aren't training them correctly.
