At the beginning of every off-season program I address our team
regarding a variety of topics to include the term “core” training.
During my presentation I ask our players not to use the word “core”
unless they are referring to the Marine Corps, the Corps of Engineers,
or my most fond Corps, the Corps of Cadets at West Point.

Herein lies an acceptable core...

When Roberta Anding, our team nutritionist, heard me say this, she
was pretty rough on me. She said, “What about the apple “core? The
players cannot say apple 'core'?” Roberta is a Registered Dietitian and
our Texans nutrition expert. She finally said “You have got to let it
go.” In the area of nutrition Roberta rules so I added apple core to the
list of acceptable corps/core items for our players.
I am unaware of the origin of the term “core training” but during the
latter part of my career it has been popularized with books, videos,
gadgets, and quackery.
During the past decade “core hype” has created frenzy over the
powerful muscles of the hips and midsection. It makes me wonder how in
the heck we got along before the “Core Nation” evolved. Have the “core
fanatics” discovered some new muscles that did not exist twenty years
ago?
A competent fitness professional must possess a minimum amount of
physiological, anatomical, biomechanical, and neurological information,
to prevent “shooting from the hip” when providing fitness advice.
Because you read something in a book, see it on a video, hear it from an
NFL strength coach, a personal trainer, or a
self-proclaimed “fitness expert”, it does not insure the information is
factual.
I have been training athletes for thirty-three years and somehow have
survived without “corelucinating.” If it sounds like I am a “core
basher” I’m not. Promoting fitness awareness for any part of the human
body is good. I have always preached balance when organizing a
strength program. Total body strength is essential for the competitive
athlete. The muscles surrounding the hips and midsection are only a
part of the equation when it comes to developing total body
strength.
I have always divided the body into five major segments to include:
1. Neck and Traps
2. Hips and Legs
3. Midsection
4. Upper Body
5. Arms
In our program we teach our players that every muscle group and all
exercises are equally important. As a strength coach, my number one
priority is short-term and long-term injury prevention. In the area of
injury prevention the muscles of the “core” are no more important than
any other muscle group in the body.
If there is a priority, and protection is a concern, the muscles of
the neck, traps, and muscles surrounding the shoulder
capsule must have the highest priority for any athlete engaged in
activities involving collisions and physical contact.
Most athletes and fitness enthusiasts understand the value of
emphasizing the core (and that is good). What is perplexing is the lack
of emphasis on more important areas of the body (and that is not good).
We often inherit players with underdeveloped and ignored neck and
shoulder muscles. Significant deficiencies exist. Isolation exercises
must be performed to target these critical areas.
In this installation of the Fitness Corner we provide information
regarding our player’s midsection routine. The midsection is primarily
made up of three major muscle groups (the Thoracic muscles are primarily
involved in breathing). They include the following:
- Trunk flexors
- Trunk rotators
- Trunk extensors
In their text, Anatomy & Physiology, Seeley, Stephens, and
Tate, list (p. 325 – 331 tables 11.8 – 11.10) the major muscle groups
moving the vertebral column and the abdominal wall. Also listed are
the major functions of each group. I do not want to bore anyone with
the anatomical names of all the muscles involved but I have included
those composing the abdominal wall.

Observe the function of the muscles composing the midsection. The
muscles of the low back and abdominal region primarily flex, rotate, and
extend the trunk.
The term “stabilizer” is another trendy “core” term used with
reverence by many fitness professionals. Do the muscles of the core
serve as stabilizers? Absolutely, however most muscles in the body serve
as a stabilizer in some capacity. Almost every muscle in our body
stabilizes to help keep us erect. If these muscles did not stabilize,
the body would collapse to the floor.
In his book Primary Anatomy, Basmajian refers to these muscles as
fixators or postural muscles. He states the following:
“A great many muscles that have nothing to do with the actual
performance of the specific feat come into play to ‘fix’ the position of
the body as a whole; these are known as fixators or postural
muscles. In most, if not all, group movements, fixators play their part.
When for example, the elbow is to be flexed, it becomes necessary to fix
(stabilize) the shoulder joint in a suitable position, in order to
steady the whole elbow region; the shoulder muscles, thus contributing
to the efficient working of the elbow flexors, act as fixators.”
Do I consider elbow flexion a good exercise to strengthen the
shoulder muscles due to their involvement as stabilizers? Common sense
tells us the answer is no. Specific exercises designed to target each of
the shoulder muscles must be performed. The shoulder strength gained is
insignificant and only at one fixed point. Basmajian calls this
additional exercise as “dubious at best.”
To generate maximum gains in strength throughout the entire muscle,
the Sliding Filament Theory tells us a muscle must be shortened
(concentrically) and lengthened (eccentrically) through its full range
of motion.
Most muscles serving as stabilizers remain in a fixed position
(static contraction). Many years ago isometric exercise became very
popular until researchers determined strength was developed only at the
specific angle the muscle was exercised at. Strength was unaffected
throughout the full range of motion of the muscles involved. Full range
exercise is not developed when a muscle is forced to exercise in a fixed
position.
For example, when one of our players properly performs a set
of negative only chin-ups for the first time, his abdominals are very
sore the next day. The abs are forced to perform a significant amount of
strenuous work stabilizing the abdominal wall during the execution of
this very demanding exercise.
Are the abs working (stabilizing) exceptionally hard to stabilize the
abdominal wall while performing a negative only chin-up? Absolutely.
Would I recommend negative only chin-ups to develop the abdominal
muscles? Absolutely not. Performing any exercise at one fixed point
violates the physiological requirements for full-range exercise.
Perform an Air Seat against the wall. Are the muscles of the hips and
legs working hard at one fixed point? Absolutely. Is this a good
exercise to develop strength throughout the full range of motion?
Absolutely not. Because an exercise is hard does not necessarily mean it
is the most productive alternative available.
Equipment manufacturers have recognized the anatomical and
physiological needs of muscles by designing structurally sound equipment
for single-joint (isolation) exercises.

Direct and rotary resistance
|
Fitness professionals must understand and recognize the need for
direct resistance and rotary resistance when exercising the
muscles of the core. Fitness professionals must also recognize the
limitation of equipment that only provides straight-line
resistance while performing a rotary movement.
We are fortunate to have a well-equipped facility. Whenever possible,
when performing an isolation exercise, try to find equipment designed to
provide direct and rotary resistance.
We teach our players to view the muscles of the midsection in the
same manner as any other muscle group. We apply the same Rep Rules for
exercises for the midsection as we do any other exercise.
- Eliminate momentum during the raising phase. For example while
performing sit-ups or ab crunches, some lifters perform what we call
throw-ups and fall-downs. Instead of raising the weight in a very
smooth manner the lifter snaps the elbows and head forward jerking the
body (this will make the exercise easier). In the starting position of
a sit-up (below) or crunch we ask our players to eliminate cheating
(eliminate the use of the head and elbows to help raise the weight) by
crossing the arms on the chest and gently tucking the head forward.
This will also put tension on the abs in the starting position. Once
you start the exercise do not allow the head to return to the ab board
until you have finished the last rep. When the head returns to the ab
board it allows the muscles to momentarily rest. It should be the goal
to make all exercises harder, not easier.

2. Pause momentarily in the muscles fully contracted position
(below). When it comes time to train the abs we sometimes see
fitness enthusiasts strap on their crash helmet and get ready to get it
on. Some people are more concerned with how many sit-ups they can
perform not realizing it is the quality (how hard) of each rep that
produces maximum gains. Some lifters snap and jerk the weight up without
pausing momentarily in the sit-up position and then effortlessly fall
back using the ab board to rebound and bounce off to throw the upper
body up again (throw-ups and fall-downs at their finest). For maximum
gains eliminate all sudden movements. Raise the weight in a very smooth
and deliberate fashion and take even more time to lower the weight.

3. After pausing in the contracted position for a count of
1001, there must be a smooth separation from the contracted position to
begin the lowering phase (no sudden drop).
4. Emphasize the lowering of the weight (take longer to lower
the weight). Lowering the weight is one-half of the exercise. Really
take your time lowering the body.
5. Consistent lowering speed from the sit-up position back to
the initial starting position.
6. Pause momentarily (do not bounce off the floor) in the
starting position before initiating the next rep.
Listed below are the basic exercises our players choose from to
strengthen the muscles of the midsection.
1. Trunk Flexion Nautilus Nitro Ab Crunch
2. Trunk Flexion Quantum Ab Crunch
3. Trunk Rotation Medx Rotary Torso left/right
5. Trunk Flexion Ab Board
6. Leg Raises
Do not straighten the legs after each rep is performed (below left).
This allows the abs to rest momentarily. Leave tension on the abs in
once you begin this exercise and keep it there until you finish the
last rep. Do not jerk the legs into the air. Raise them in a very slow
smooth and deliberate manner and then pause for a count of 1001 in the
contracted position (below right).
7. Trunk Extension Medx Low Back
8. Trunk Extension Back Extension
Our standard midsection routine incorporates the following sequence.
Any additional exercise (leg raises or more than one crunch) is
optional.
1. Trunk Flexion – 12 – 15 reps
2. Trunk Rotation – 12 reps
3. Trunk Extension – 12 reps
In the past I over-trained the abdominals. I assumed that the abs
needed hundreds of reps to reach their maximum potential. I have learned
the hard way (after wasting significant time on non-productive
exercise). To increase the strength of any muscle, overload must be
provided (more weight/and/or more reps). Too many reps (time under load)
and muscle endurance will improve but not the anaerobic strength and
power.
If a person continues to use his/her bodyweight, the muscles of the
midsection will eventually adapt to the weight of the torso. The
abdominals (or low back muscles) will eventually stop gaining strength
if more resistance is not applied.
Our players can increase the resistance for each of our ab and low
back exercises by as little as one-pound increments.
I often observe fitness enthusiasts performing multiple sets of
(throw-up and fall-downs) crunches and side crunches with their
bodyweight. It burns every time but the weight of the torso has not
changed. There is no additional overload and therefore no additional
strength gain.
It does not guarantee improvement because an exercise burns or hurts.
Hold your arm out in front of you with a very light dumbbell and perform
small arm circles. Continue to do this each workout. It burns and hurts
but eventually little benefits will be derived.
Like all exercises our players perform, we document the amount of
weight used and the number of good reps completed. When a player can
complete the designated number of good reps, we must add weight, if the
goal is to continue to gain strength.
This was not easy. After getting blasted by our team nutritionist, I
agreed to stop my “Ignore the Core” campaign. But I told Roberta if, and
only if, the “Core Nation” agrees to place equal emphasis on the muscles
of the neck, traps, and muscles crossing the shoulder capsule.
Gotta go. It is time to go work my core.
