Practice Abdominal exercises for a Flat Stomach

Are there exercises for your stomach?
I will explain you in a moment but first let me tell you about the advantages of abdominal exercises.

Why there are only three best flat stomach exercises and not just one?
Your abdominal muscles best respond to exercises that concentrate on each part of your abdominals, the upper abdominals, the lower abdominals and the obliques (commonly known as the love handles). Even though your upper and lower abdominals are actually one single muscle the best way to train them is with exercises that concentrate on each part individually as each part of your abdominals needs a slightly different stomach exercise to train most effectively, that's why I have chosen these three exercises.

Are there any other abdominal exercises?
There are many abdominal exercises some are more effective then others, there are simple exercises for beginners and harder exercises for more advanced athletes.

Exercise: 1
Best Upper Abdominals Exercise: The Basic Crunch

Lie on your back on the floor or on an exercise mat with your hands to the side of your head or crossed on your chest. Keep your knees bent at a 90 degree angle with your feet resting on the floor.

Lift your shoulder blades of the ground as if you are trying to touch your knees with your chest but do not move the legs. Concentrate on lifting using your stomach muscles only.

At the top of the movement contract your abdominal muscles intensely and then slowly lower your body down. Lightly touch the floor with your shoulder blades and repeat.

Repeat 15-30 times. Breathe out on the way up, in on the way down. Rest a few minutes and do another set. Try to do 3-4 sets.

If you are a beginner or if this is hard for you, do 10 repetitions for one set and gradually work your way to the recommended amount of repetitions.

When doing this abdominal exercise it is important that you don't actually sit up all the way. When you sit up your hip flexors do most of the work and it can be bad for your back.

Exercise: 2
Best Lower Abdominals Exercise: The Reverse Crunch
Lie on your back on the floor with your hands behind your head or on the floor by your hips, with your knees bent and your feet lifted six inches above the ground.

Slowly bring your knees toward your chest and lift your butt of the ground. Concentrate on contracting your abdominals; you should feel your lower abdominals working after a few repetitions.

Use your abdominals do not swing your legs to create momentum. Slowly lower your legs to the starting position, six inches of the floor.

Repeat 15-30 times. Breathe out on the way up, in on the way down. Rest a few minutes and do another set. Try to do 3-4 sets.

If you are a beginner or if this is hard for you, do 10 repetitions for one set and gradually work your way to the recommended amount of repetitions.

Exercise: 3
Best Obliques Exercise: The Oblique Crunch
Lie on your back, knees bent, so your left foot is resting flat on the floor. With your right knee bent, place your right foot across your left knee.

Place your left hand at the side of your head and your right hand on the left side of your abdominals or on the floor next to your thigh.

Curl your body up with a twisting movement, bringing your left shoulder toward your right knee. Slowly lower your body to the ground.

Repeat 15-30 times. Breathe out on the way up, in on the way down. Rest a few minutes and do another set. Try to do 3-4 sets.

If you are a beginner or if this is hard for you, do 10 repetitions for one set and gradually work your way to the recommended amount of repetitions. Don't forget to do the same for the other side as well.

Bonus: The Bicycle Exercise
This is a simple and very effective exercise that works all three areas of your stomach simultaneously.

Lie on your back on the floor with your hands behind your head. Slightly bend your knees and bring them in towards the chest and lift the shoulder blades off the ground.

Straighten the left leg out to about a 45-degree angle while simultaneously turning the upper body to the right, bringing the left elbow towards the right knee.

Switch sides, bringing the right elbow towards the left knee. Continue alternating sides in a 'pedaling' motion for 15-30 reps. Rest a few minutes and do another set. Try to do 3-4 sets.

If you are a beginner or if this is hard for you, do 10 repetitions for one set and gradually work your way to the recommended amount of repetitions.

I would advise to consult your physician before starting any new exercise program.
It is recommended that you do the lower abdominal exercises and the oblique exercises before the upper abdominal exercises.

Hope you can get a flat stomach and great abdominals without buying any exercise machines. Some of them don't work and most of them aren't more effective then the regular crunch.
