abdominal crunches

Abdominal crunches are one of the most common ab exercises. They may be more simple than other stomach workouts but can be very effective if done correctly.

If you are looking to flatten your stomach then check out these abdominal exercises. These are some of the more common stomach exercises.

They 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.

Most people think of this as separate muscles with upper abs and lower ab muscles. This is actually one long muscle.

So when performing crunches, you will be working the entire muscle but with a focus on the upper or lower area of this muscle.

Advantages & Disadvantages of Abdominal Crunches

Some of the advantages to doing 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 stomach 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.

Yet 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.
