Iowa's problem is they are so 80's, the whole "work harder" and ignoring the modern way to train, that is "work smarter, not harder". Nolf on the "Wrestling Changed My Life" podcast stated that PSU practices are about 90 minutes. Sure they are doing some work on their own, but bottom line, they are not getting the hell beat out of them. Most people like avoiding the grind. Nolf went from working out/practicing for 4 hours a day in high school to 90 minutes at PSU. Same story for David Taylor.
The Iowa 80's style worked in the 80's because that is how everyone trained.
I coach high school track, run into the same stupidity. I train sprinters with a low volume, high instensity workout. Head coach hates it and says "that isn't how I trained." Head coach graduated high school in the late 70's. I point out that THE Carl Lewis (HC at Houston) says that sprinters today do not do nearly the volume that he did in the 70's and 80's. He still refuses to accept it.
Dinosaurs kill athletes. I hope Iowa continues their 80's approach.
