THE ABDOMINAL TRAINING FAQ

This FAQ is intended as an introduction to the basic principles of training
the abdominal area, sometimes known as the belly or the abs. The creation of
this FAQ was motivated by frequent questions on the topic in the newsgroup
misc.fitness.

The FAQ is posted every month to misc.fitness and misc.answers. It is also
available via anonymous ftp from rtfm.mit.edu in
/pub/usenet/misc.fitness/Abdominal_Training_FAQ. Those preferring to use

I. INTRODUCTION AND CAVEATS

The information in this FAQ is based on

   Health For Life's _Legendary Abs_ booklet
   endless threads about abdominal training
      in misc.fitness and
      on the weights mailing list
   and sundry other sources.

See the references list at the end for how to get hold of these things for
yourself.

II. QUESTIONS

QUESTION 1: How do I get abs like giant ravioli?

Getting visible abdominal muscles or "abs" depends on reducing the amount
of fat covering the abs, see Question 3. Getting hard, lumpy abs depends on
developing the underlying muscles, for details, read on...

QUESTION 2: Should I do lots of situps to reduce fat around my
middle?

No. Exercising the area from which you want to lose fat is called "spot
reduction". Spot reduction is now believed to be a myth. Research shows that
fat is lost all over your body, not just in the area that you work. Situps are
also bad for your lower back (see Question 5).

QUESTION 3: How do I reduce the fat covering my middle?

The answer comes in two parts: diet and aerobic exercise.

DIET

This is controversial, but most people agree that eating very little fat and lots
of complex carbs (like rice, pasta and potatoes) helps ensure that you don't
add additional fat. Then you have to work at using the fat you already have
stored which involves...

EXERCISE

Again a bit controversial, but it's widely agreed that regular, moderate,
aerobic exercise 3-4 times per week works best to burn fat that's already
stored.

"Moderate" because intense exercise burns glycogen not fat, so keep the
intensity at about the level where you are beginning to puff a little.

"Aerobic" means (very vaguely) the kind of exercise that requires you to
inhale more. Some suggest that building more muscle through weight
training helps as well, since muscle burns fat just by being there and moving
your body about; so some weight training couldn't hurt and will probably
help.

Many misc.fitness people agree that exercise periods of more than 20
minutes work best. But note that the longer you exercise, the more prone you
are to injury since your muscles also begin to weaken. Two things which
help prevent injury are:

a good warmup
   5-10 minutes of light exercise to warm your muscles, try to break a
   sweat
stretching
   cautious 20-30 sec stretches for every muscle (for an excellent source
   of information on the topic, see the Stretching FAQ).

QUESTION 4: How do I exercise the abs?

The abs are designed to perform one main task, to shorten the distance
between your sternum, or breastbone, and your pelvis. The only way to do
this is to bend your spine in the lower back region.

In short, any exercise which makes you move your sternum toward your
pelvis or your pelvis toward your sternum is good. To do this safely, the
lower back must be rounded, not arched.

QUESTION 5: What's wrong with situps?

Traditional situps emphasize sitting up rather than merely pulling your
sternum down to meet your pelvis. The action of the psoas muscles, which
run from the lower back around to the front of the thighs, is to pull the
thighs closer to the torso. This action is the major component in sitting up.
Because of this, situps primarily engage the psoas meaning that they're
inefficient and grind vertebrae in your lower back.

They're inefficient because the psoas work best when the legs are close to
straight (as they are when doing situps), so for most of the situp the psoas are
doing most of the work and the abs are just stabilising.

Putting the thighs at a right angle to the torso to begin with means that the
psoas can't pull it any further, so all of the stress is placed on the abs.

Situps also grind vertebrae in your lower back. This is because to work the
abs effectively you are trying to make the lower back round, but tension in
the psaos encourages the lower back to arch. The result is the infamous "disc
pepper grinder" effect that helps give you chronic lower back pain in later
life.

There may be a way to do situps safely and thus exercise your psoas muscles.
If anyone knows what it is, please let the FAQ maintainer know.

QUESTION 6: What are good ab exercises?

For the lower abs, in order of difficulty:

   15cm lying leg raises
   vertical lying leg thrusts
   hanging knee raises
   hanging leg raises

For the upper abs:

   ab crunches
   1/4 crunches
   cross-knee crunches
   pulldown crunches

15cm Lying Leg Raises

Lie on your back with you hands, palms down under your buttocks. Raise
your legs about 30cm off the floor and hold them there. Now trying to use
just your lower abs, raise your legs by another 15cm. Do this by tilting the
pelvis instead of lifting the legs with the psoas. Make sure your knees are
slightly bent.

If you're big or have long legs or both, you should probably avoid this
exercise. For people with legs that are too heavy for their lower abs strength,
this exercise pulls the lower back into an arch which is bad (and painful). For
reasons why it's bad, see Question 5. If you have this problem you can either
try bending your knees slightly and making sure you keep your lower back
flat, or just try another exercise.

Vertical Lying Leg Thrusts

Lie on your back and put your legs in the air vertically over your pelvis and
your fists at your sides on the floor. Now, just using the abs raise your pelvis
off the ground. If you have difficulty straightening your legs, that's OK, but
make sure you're doing the work with your abs, not using the momentum of
thrusting with your legs. Try pointing your toes at the top of the movement.

Lie on your back with your fists, palms down, under your buttocks to keep
your lower back flat against the ground. Try to raise head and shoulders off
the ground.

With your knees slightly bent, raise your legs 35 to 45cm off the floor. Your
lower back should be flat against the floor; if not, bend your knees more or
raise your legs higher.

The exercise itself has four phases:

 1. Contract your abs to raise your pelvis and legs so that your feet are
   pointing at the sky.
 2. Thrust upward with your pelvis, pushing your feet skywards.
 3. Lower out of the thrust, leaving your pointing up.
 4. Lower your pelvis and legs back to the starting position.

Legendary Abs II recommends these as safer than Lying 15cm Leg Raises.

Hanging Knee Raises

You need a chin-up bar or something you can hang from for this. Grab the
bar with both hands with a grip a bit wider than your shoulders, cross your
ankles and bring your knees up to your chest (or as close as you can get).
Your pelvis should rock slightly forward. Pause at the top of the movement
for a second and then slowly lower your knees by relaxing your abs. Don't
lower your legs all the way. Repeat the movement using just your abs to
raise your knees.

Make sure that you don't start swinging. You want your abs to do the work,
not momentum. It's important that you don't move your legs too far or your
psoas muscle will be doing a lot of work and possibly causing back problems
as in a situp. Make sure your pelvis moves, your lower back stays roudned,
not arched, and that your abs are doing the work, not your hips.

Hanging Leg Raises

Just like knee raises except you keep your legs straight. This requires good
hamstring and lower back flexibility, see the Stretching FAQ for details.

Although Legendary Abs recommends these, The American Council on
Exercise's Aerobics Instructor book warns that they have the same back
problems as conventional situps. This makes sense since, like situps, the legs
are kept straight and the hips move. For safety you should probably stick to
leg thrusts and knee raises.

If you do them, make sure your lower back stays rounded.

Ab Crunches

Lying on your back, put your knees up in the air so that your thighs are at a
right angle to your torso, with your knees bent. If you like you can rest your
feet on something, like a chair. Put you hands either behind your head or
gently touching the sides of your head.

Now, slowly raise your shoulders off the ground and try to touch your
breastbone to your pelvis, breathing out as you go. If you succeed in touching
your breastbone to your pelvis, see a doctor immediately.

Do these fairly slowly to avoid using momentum to help.

1/4 Crunches

Same as an ab crunch except that you raise your shoulder up, instead of
pulling them toward your pelvis. You can do these quickly, in fact it's hard
to do them any other way.

Cross-Knee Crunches

Like ab crunches, take the lying, bent-knee position, but this time crunch
diagonally so that you try to touch each shoulder to the opposite hip
alternately. At the top position, one shoulder and one hip should be off the
ground.

Pulldown Crunches

Drape a towel or rope around the bar of a pulldown machine so that you pull
the weight using it instead of the bar. Kneel facing the machine and grab
hold of the towel and put your hands against your forehead. Kneel far
enough away from the machine so that the cable comes down at a slight
angle.

The exercise is the same movement as an ab crunch, but using the weight
instead of gravity. The emphasis is still on crunching the abs, pulling the
sternum (breastbone) towards the pelvis making sure you exhale all your air
at each contraction.

QUESTION 7: Is there a specific order I should do exercises in?

According to the Health For Life people, you should exercise the lower abs
before the upper abs and do any twisting upper ab movements before straight
upper ab ones. Twisting exercises work the obliques as well as the upper abs.

QUESTION 8: How do I structure a routine?

   Try to do sets in the 15-30 rep range.
   Follow the two golden rules in Question 7.
   Pick easy exercises to start with and when you can happily do about 2
   sets in a row of an exercise, try picking harder ones.
   Only rest when you absolutely must, so take a short (10-15sec) rest
   between two sets of the same exercise, but none between lower and
   upper abs.
   Try to take about 1 second for each rep, except for ab crunches which
   you should always do slow (2 secs/rep) and 1/4 crunches which you
   should do fast (2 reps/sec).

QUESTION 9: How often should I train abs?

Some writers recommend doing abs at every workout. Others recommend
doing them however often you do anything else in other words treating them
as you would any other body part. Health For Life's Legendary Abs
recommends three or four times a week.

QUESTION 10: Should I do side bends to reduce my love handles?

Nope. Love handles (the pads of fat above the hip bone at the side of the
waist) are fat and only shrink with a low fat diet and general aerobic exercise
(see Question 3). You can't just remove the fat from that area on its own.

As well as that, side bends build the obliques under the fat and will make
your love handles look bigger. Direct oblique exercises are generally
considered a bad idea for that reason, but if your aesthetics for the human
body include big, meaty obliques, then go right ahead.

QUESTION 11: Gee, but shouldn't I balance my abs with my spinal
erectors?

Thanks for asking. If your develop your ab strength without similarly
developing your spinal erectors (the muscles that straighten your lower
back), you will end up with strange and possibly damaging posture.

A fairly good lower back exercise is hyperextensions, which are best done on
a hyper extension bench, but can be done on a bed or ordinary bench with
something (or someone) holding down your ankles.

Lie face down, with your hands touching the sides of your head, your body
draped over the edge of the bench and with your hips supported so your
pelvis can't move. Slowly raise your torso to the horizontal position, but no
higher.

Keep your head, shoulders and upper back arched through the whole
movement.

Try to do a couple of sets af around 12 reps after each ab routine or after
each back routine. Don't exercise them more than about three times a week.

If you already do deadlifts that's probably exercise enough.
