You can do crunches until you can't bear to stand up, but you won't develop a flat stomach unless you also burn the fat around your middle. On the other hand, because there are no bones associated with stomach muscles, any strengthening of them will be noticeable to a point. You should adopt a nutritious diet and add aerobics to your commitment of crunches and other ab exercises if you want to show off your hard belly.
Isometric Ab Exercise
The best ab workout for men begins before you even get to your gym or workout area in your home. Isometric exercises can be done anywhere, whether you are standing up, sitting down and lying flat on your back. Simply tighten your stomach muscles and hold for 10 to 30 seconds. If you will make a concerted effort to remember to do this throughout the day, you will see evidence of its effect within a month.
Crunches are the backbone of an ab workout and though they won't do the trick alone, they should not be avoided. Crunches are actually very useful because you can do them anywhere you can find space to lie flat on your back. Clasp your fingers behind your head and slowly curl your torso as you tighten your stomach muscles. Crunches differ from old-fashioned sit-ups in that you need only lift your shoulders up off the floor instead of most of your back.
Slanted Bent-Knee Sit-Up
The slanted bent-knee sit-up requires a weight bench that can be slanted. Set the board so that you can maintain a position of bent knees throughout the set. Keep your hands folded across your chest as you bend at the waist and do a full sit-up. Make sure that you are using your ab muscles to pull yourself forward and don't make the mistake of rocking your body in order to pull yourself up.
Hanging Knee Raise
Hanging knee raises are an advanced exercise for developing your ab muscles. This exercise is done by hanging from a bar with your hands and keeping your feet off the floor. While hanging, you should bend your knees and draw them up toward your chest. Hold for a count of two and then return to the stating position, making sure that your feet do not touch the ground.
The twist exercise gives your oblique ab muscles a good workout. Sit on a weight bench with a barbell resting on your shoulders. Twist first in one direction and then in the other direction. Keep your spine straight as you engage in this exercise. As you become more adept you can start to add some weight to the barbell, according to the book "Basic Weight Training for Men and Women."
