The problem is most of these guys aren’t going to reach their full potential because they have no muscle. The ones eventually hitting big numbers are going to be those who already have muscle. which does not mean they’re the genetically elite, but can be due to a lot of factors like activity level and eating habits while growing up.
Thus, it still goes back to the internet. If people start out building a base of muscle and then specializing in the main lifts instead of going, “I’m powerlifting, not hypertrophy training”, we’re probably going to see an increase in the lifts of the average lifter. But, no, people turn this shit into cult-like beliefs and spread dogma, and internet writers are capitalizing on it by telling them what they want to hear.
To top it off, here’s the best part: most of what I read about “hypertrophy training” is bullshit too.
God bless the internet.
