Abdominal Crunches
Abdominal
Crunches
- The Most Common Abs Exercises
If you are looking to flatten your
stomach and get a great set of abs,
then check out these abdominal exercises. These are some of
the more common stomach exercises and
will work
both the upper and lower abdominal muscles, or your rectus abdominis
muscle.
The
rectus abdominis is often referred to as your six pack abs and most
people think of this as separate muscles with upper abs and lower ab
muscles. But in fact, this is actually one long
muscle. So
when performing abdominal crunches, you will be working the entire
muscle but with a focus on the upper or lower area of this muscle.

The traditional crunch works your rectus abdominus
muscle. It is
one of the most common abs exercises and is believed by many to be one
of the most effective. However, you may want to read the
results of one study on the best ab exercises before you make up your
mind on which is the best abdominal exercise.
How

- Lying flat on the floor, make sure your lower
back is pressed to the floor and is not arched.
- Place your hands loosely behind or beside your
head.
- Bend your knees and place your feet flat on the
floor.
- Exhale while you curl your body forward off the
floor making sure your shoulder blades come off the floor.
- Hold for one second and then slowly return to
starting position, inhaling while you return to the floor.
- Repeat this for 8 to 15 repetitions.
Note: If you have not done many abdominal exercises for
awhile, the traditional crunch is a great exercise to start with to
help strengthen your core and back before moving on to more challening
ab exercises.

Advantages
and Disadvantages of Abdominal Crunches
|
|
Some
of
the advantages to doing abdominal crunches is it requires no
special
abdominal exercise equipment. All you need is a spot on the
floor and an exercise mat.
Another great advantage to
abdominal exercise crunches is there is less stress on the lower back
than some more
advanced or challenging abdominal exercises.
|
Some of the disadvantages of doing abdominal crunches is the
limited range of
motion. The crunch requires very little movement of the spine
and stomach, which limits the area of muscle worked. Another
disadvantage to crunches is that it requires no additional resistance
in the form of weight or an exercise ball.
Therefore you can
outgrow or plateau your strength training on these abdominal muscles.
If this happens, try using an exercise ball or add some
weights to your crunches.
