I tend to agree with him, and here's why: First, you have to read what he says in context- otherwise it just sounds like he's saying BJJ sucks. He's not. Mr. Zahabi is himself a BJJ blackbelt. No one earns that rank without a trial by fire- let alone respecting the art.
2. A very small percentage of the grapplers and fighters I know who started in BJJ can wrestle well. A large percentage of the grapplers and fighters I know who started in wrestling can do BJJ well. It's a personal anecdote, but that's been my experience.
3. But let's talk about strength and conditioning for a moment. In every major sport, the athletes will dedicate a significant portion of their training time to strength and conditioning (ie: picking up heavy stuff and moving it in order to get stronger, faster, etc... ) however, with some notable exceptions, BJJ competitors do not. In fact, I would go as far as saying most martial artists do not spend the kind of time in the weight room that they should.
That's really weird to me. I played baseball a lot when I was a kid. There is athleticism involved, but not quite enough in my opinion to merit looking like the Incredible Hulk. In baseball, the body is only in motion for very brief intervals. So yes, it pays to be able to sprint fast and hit hard- but the small amount of work done on the field relative to the large amount of done in the weight room in baseball is widely disproportionate.
Grappling, on the other hand, is a sport where the body is in constant motion, constantly under pressure, and constantly meeting resistance. Technique is first and foremost in all sports- but it's no secret that strength and athleticism augments an athlete's ability to use their technique to its maximum potential. So you would think that more BJJ competitors would spend more time doing deadlifts.
^Just in case you've never seen baseball players before^
To this I say (1) wrong. Moving your body in any way, shape, or form requires power. All grappling techniques are applications of power. These folks are confusing "power" with "working against leverage". Good technique is an efficient application of power. Bad technique is an inefficient application of power. But all technique is a use of power.
(2) Strength training keeps you healthier for longer. There are all kinds of scientific studies and endless anecdotes confirming this. There is a direct correlation between neuromuscular strength and physiological health. If you want to roll till you're old, then you've got to make yourself athletic enough to do the work, to take the punishment, and to recover properly afterward.
We're all impressed when we see a little guy beat a larger stronger opponent with awesome secret ninja moves. But when everyone knows the same moves- the better athlete wins.
