The Rectus Abdominis muscle is the most noticeable muscle in your abdominal region if you've reduced your bodyfat sufficiently to reveal the muscle.
Your abs can be more impressive by the proper selection of certain abdominal exercises.
Although the Rectus Abdominus is one long muscle, it's divided into four segments on each side.
The top three segments on each side are most noticeable as your "six-pack.
The Reverse Crunch exercise is very effective in developing the lower part of your six-pack if performed correctly.
To begin the exercise, lie on the floor with your upper and lower legs bent at a 90-degree angle with feet flat on the floor.
Place your arms at your sides on the floor.
This is the "start position".
Using your abdominal muscles, rotate your upper thighs toward your torso, while keeping the upper and lower legs bent at the 90-degree position.
Attempt to bring your thighs up to your chest as close as possible, while trying to lift your buttocks off the floor.
At first, you may not be able to lift your buttocks off the floor.
However, as you become more conditioned, you will.
This exercise uses the abdominal muscles to tilt the pelvis forward, which lifts the buttocks off the floor.
This is the "finish position".
When rotating your thighs toward you, make sure that the motion is very slow.
Do not pull them up fast in an attempt to force your buttocks off the floor.
Let your abdominal muscles do all the work.
If you rotate your legs too fast toward your chest, you risk placing undue stress upon your lower spine and causing injury to your discs.
After achieving the "finish position", slowly return your legs back to the "start position", while keeping the upper and lower legs locked in the original 90-degree position.
Now, you have completed one repetition.
However, after performing the first repetition, do not rest your feet on the floor.
Begin the next repetition by just touching your feet to the floor and then immediately begin your thigh rotation back to your chest ("touch and go").
As you become stronger and can lift your buttocks off the floor, you can add a dumbbell between your feet for extra resistance.
However, do not compromise form and technique just to lift more weight.
The Reverse Crunch, if performed properly, will stimulate the lower abs to help you attain the much-desired six-pack look.
