Interesting article. I'm not really knowledgeable enough to agree or disagree on most of what he wrote lol. But it makes sense.
It got me thinking about a sport like BJJ though, Where (IMO) the stronger you get the less advantageous it gets to spend more and more time into getting stronger (compared to when you started.) In other words, if it took you a year to go from 185lbs squat to a 350+ lbs squat, then that's a great deal of increase. However if you then trained the same amount of time for another year and only got 50 more lbs on your squat. You did indeed definately get stronger, but it seems like diminishing returns for your time investment (obviously it gets harder to improve the stronger you get.)
Where is, or how would you determine the line for when you should switch focuses from absolute strength, to more of explosion and power or muscular endurance (note on switching FOCUSES, not saying you shouldn't be doing some of this all along). Now I know it's probably a highly personal thing as to where this line would be, along with what type of game plan you employ. But I was just curious as to what y'alls opinions are on that.
