I've been a long-time fan of Herman's, but he sure makes it hard to be a fan.
His offbeat, comical way is part of his appeal. The "I only trained a few hours in my garage" stuff worked before he went to the UFC, but he should've abandoned that long ago. It would be OK to claim he doesn't train (sort of an Andy Kauffman routine), but he should secretly be in the gym all the time regardless.
I do think he trains (or used to) a little more than he admits. You don't pull of an omoplata or athletic high kick if you only run or lift. However, he clearly doesn't train enough or with any consistency. And he actually looked better in his pre-UFC fights. Of course, better opponents make unorthodox stuff harder to pull off, unless you train like Jones, Machida or Anderson.
To make matters worse, he took very short-notice fights against veterans like Nelson and Big Nog. Before the Nog fight, he said something like "a 3-week camp is perfect for me." That's probably all he trained between the Nelson and Nog fights.
This just kills me: "I have other stuff going on...I don’t really have a place I can go to spar or anything. I’m not trying to go to a gym everywhere. This is fine.”
Uh, you're in your physical prime and MMA is your job. What else could be more important? Are you writing the next great novel or going to law school on the side? Sheesh.
