De-Assification of America (from ArthurDevany.com):
Buns:
"Young women love them in a man. Evolutionary
psychology tells us they should. Strong and solid buttocks are a sign of health
and power in a male. But, buns seem to be shrinking these days. I am struck by
the lack of glutteal musculature in males these days. The pants just hang on a
lot of the softball players I see.
A male can't be powerful unless he has developed buttocks. They are the
foundation of mobility for almost all athletic moves and they are the prime
movers in any rapid or powerful move. Heavy lifting, sprinting, hitting or
throwing all move off the drive from the legs and gluts.
Why are buns shrinking?
1. Too much sitting. Sitting cuts off the blood supply to the gluts and
they atrophy. They just waste away from a lack of blood flow. Go into a truck
stop and you will see men that may have started driving as young, tough truck
jockeys whose pants just hang straight down from their belt after 20 years in
the cab. Office workers are just as vulnerable.
2. Too little full body exercise. Deadlifts, squats, splits, power
cleans, and overhead moves engage the gluts. Sitting in a leg extension machine
does not. Hack squats on those slanted racks were designed to avoid developing
the glutes by bodybuilders seeking a Steve Reeves look.
3. Not enough sprinting. Glutes are essential to a powerful and full leg
drive. Jogging doesn't do it. Running at varying speed does to some degree. Long
term joggers tend to have a tucked under pelvis, tilted forward from the base,
probably to protect their lower back. This reduces engagement of the glutes.
4. Too much alcohol. Alcoholics have no glutes. Check it out. They do all
of the above: sitting, not exercising, no sprinting. But, they have another
problem. They are so malnourished, particularly in protein, that they consume
their own muscle mass to maintain their overworked organs. Their organs are busy
trying to detoxify their bodies and are overloaded.
One of the strangest sights I have ever seen was inside one of those bars that
open at 6:30 in the morning. I was delivering beer kegs in one of my summer jobs
and went into one of those bars to make a delivery. At 8:00 in the morning there
were drinkers sitting at the bar. What strange creatures they seemed to my
inexperienced eyes. They didn't speak, they croaked from free radical damage of
smoke and alcohol to their vocal cords. They had florid faces (blood vessel
damage, again from ROS). They had bloated bellies from protein deprivation and
liver damage. And, they had no glutes.
With the stench, dark, smoky air, and bar lighting, I felt like I was in another
world populated with strange creatures. I have never forgotten it.
I know two famous economists who drank themselves to death and a few who tried
(high level economics is hard to do and economists are contentious, hard-headed
people; economics seminars often are a blood sport). Out of respect, I won't
mention their names.
In their decline, they manifested all the signs of these pitiful and strange
people in the 6AM bar. Their florid faces gave them a look of health, they
almost looked tan. Their bellies made them look robust. But, their glutes always
gave them away; they were dying alcoholics.
So, women are right. Buns are good. They are a very reliable sign of health and
power in a male; good genes and provision to a female in the evolutionary
environment where buns would have been a powerful clue."
America the "gluteless society
"To be blunt, most Americans have absolutely no posterior chain
development!"
To squat properly, you need to sit back. To sit back, you need to have strong
glutes and hamstrings. A study by Caterisano indicated that the deeper you
squat, the greater the glute activation becomes. Along with that, the more
shallow you squat, the greater the quadriceps activation (~70% quads in a
quarter-squat as compared to ~50% quads in a full squat).
If you're just plain weak, you need to focus on glute-ham raises, Romanian
deadlifts, good mornings, reverse hypers, full squats, and basically any other
exercise which works to develop the posterior chain. If your technique is poor,
box squats are an excellent exercise to teach you the proper motor pattern as
well as developing the posterior chain.

Reasons for the Difference...
Firstly, I acknowledge that there is a genetic component to the Bushman's
gluteals. (Refer: "Steatopygia" also "Social & Clinical Comments" .) But it is
the behavioral component of "Bushman's gluteals" that I wish emphasize here.
After all, we cannot change our genes, but we can change our behavior!
The large gluteals in the bushman are due to two identifiable causes
Bare-foot walking
Routine squatting while at work.
Both of these will be discussed with special emphasis on the lessons that can be
learned about modern western musculo-skeletal health.
