His lower back is genetically shit. Which is why he will never win an Olympia.
Genetics and muscle insertions are every bit as important, as size and conditioning.
I beg to differ. Rhoden came on the scene a little bit later. You normally see backs like his when the bber doesn't train it like the others (intensity, mind-muscle connection, work the middle)---Phil, Ronnie, Shawn Ray, Dex, Flex, Cormier, Kai, Dorian, etc. But, when one trains like Jay one gets Jay Cutler like results.
