IMO, I think the time thing is an essential element too. That's because the biggest problem with the complex lifts is the stubborn insistence that all body types can and should lift the same way. “Ass to the grass!”
Now let’s all acknowledge some guys are just stronger than others, even though they appear to be built the exact same way. That’s just life and not what I’m talking about.
The argument often gets sidetracked when it is reduced to tall vs short, but that is not the issue at all. Exaggerating obviously, but Zach Martin basically has the same proportions as Audric Estime, which is why he is paid millions of dollars to block in the NFL!!! Tall and wide may obviously be more advantageous than short and skinny.
It’s really about alll kinds of things like bone thickness, body proportions, joint angles, etc. Its related to why high jumpers jump off one foot, while thicker guys tend to dunk off two.
For example, when a guy has very short legs and a long torso, his spine doesn’t have to bend as much when he is back squatting—and glutes engage more naturally. When a guy has long legs and short torso, he either has to lean forward or bring his knees way out over his feet to keep from tipping over (pure physics). All of this so he can get below parallel, which (as I understand the history) is a somewhat arbitrary finishing point chosen to ensure an objective “complete” lift for lifting competitions. Forcing that guy to crank out reps like a more ideal body type is questionable, IMHO.
It’s the rare football coach who has enough time or resources to teach the right way to lift for each kid, which ends up favoring certain body types over others (see Brendan Vernon’s strength being questioned ).
