Charlie is mentioned a few times throughout the article⌠Some interesting info.
Most experts in the fitness industry fail to recognize the role that the load vector plays in
determining hip extensor recruitment during hip extension exercises. As a case in point,
most articles written on glutei maximi training recommend axial loaded exercises such as
squats, deadlifts, and lunges. But axial exercises are greatly outperformed in glutei
maximi mean and peak activation by anteroposterior exercises.I donât expect the experts to know this, as to my knowledge, I am the first author who is pointing this out
scientifically. Although itâs been hinted about by strength coach Mike Boyle in the past
and recently inferred (during the time I was writing this book) by vertical jump specialist
Kelly Baggett, and although there have been many small-scale EMG studies performed in
the scientific literature, to my knowledge a large-scale EMG study involving dozens of
advanced and complex hip extension exercises has never been disclosed to the public â
until now.I will discuss specific exercises and EMG data later in this book, but first letâs continue
talking about load vectors.I just performed a Google search for âbest glute exercisesâ and the first article that came
up was a web document written by Ray Burton, an ISSA Certified Trainer out of Canada,
entitled âGlute Exercises â My Top Three Choices.â His top three choices are reverse
lunges, sumo squats, and a special step up (a hybrid step-down/assisted pistol
movement), which are all axial loaded exercises.Iâm not trying to pick on Burton, as
articles like these are littered throughout the Internet and forums. If you gave me a full
day, I honestly believe that I could print out 300 articles, blogs, or forum posts that listed
axial hip extension exercises as the absolute best glute exercises.Furthermore, I just took a trip to Barnes and Noble and spent about three hours flipping
through every popular book on strength training. I found books written by popular
authors including Mark Verstegen, Pavel Tsatsouline, Nate Green, Lou Schuler, Ian
King, Mike Mejia, and Menâs Health experts. Although every single book explained
ways to provide extra loading to axial hip extension exercises, not one of them showed
ways to provide extra loading to anteroposterior hip extension exercises. For some reason,
our industry feels that we should load up squat, deadlift, and lunge (axial)
movements but we should be content to stick to bodyweight bridge, quadruped, and
hyperextension movements. Has anyone stopped to think how idiotic this is?Thank God for Louie Simmons or weâd never even consider loading the anteroposterior
vector (Simmons helped popularize weighted reverse hypers, back raises, pull throughs,
and glute ham raises).In his article entitled âSquats and Speed?,â Kelly Baggett stated the following:
[QUOTE]âSquats allow one the biggest bang for the buck when strengthening and adding
size to the glutes, quadriceps, and hams all in one shot in that order and thatâs why
they are so effective initially.â
In The Butt Book, fitness author Tosca Reno states:
âYou must learn to love squats. Performed correctly, squats will endow you with
the best backside results when redesigning your glutes. Many of us have flat, even
non-existent backsides that must be coaxed into curviness by performing the
regular back squat.â
Later, she says:
âThe best butt-mass builder is the back squat.â
In his article entitled, âGet a Great Ass,â popular trainer/author Chad Waterbury stated
the following:
âThe deadlift is most effective gluteus maximus builder known to man â or woman.â
In fact, a YouTube video shows a lean Monica Brant (figure and fitness competitor and
cover model) doing deadlifts with 135 lbs and you can see her glutes contracting during
the set.
You can tell that her glutes are not contracting maximally (enough to exceed how hard
she could contract them on her own, which is known as maximal voluntary contraction or MVC).
If she were using the same amount of weight
with hip thrusts (which I will teach you later), her glutes would contract much harder and she would most likely exceed MVC.
I should say that Waterbury redeemed himself in his last article entitled, âThe Fast Track
to a Hard Ass,â where he recommended sprints, swings, and bridges; three
anteroposterior hip extension movements.
However, he attributes the superiority of these
exercises as glute developers to their explosive contractions and fails to mention the role
of the load vector.
There have been several authors who have raised the issue of load direction. Legendary
biomechanist Vladimir Zatsiorsky stated that one of the advantages to sprinting
parachutes over other methods of resistance training is:
âThe resistance (drag) force acts strictly in the direction of the athleteâs
movement.â
Speed coach and entrepreneur Lauren Seagraves stated in his article entitled,
âNeuroBiomechanics of Maximum Velocity,â that the four primary objectives to increasing maximum velocity are:
- Apply greater force
- Apply the force in less time
- Apply force in the proper direction
- Apply force through the full or optimal range of motion.[/QUOTE]
