Despite the headlines in popular magazines that offer empty promises of "Flat Abs in 10 Days," thinking that you can create toned and defined abs with a series of endless crunches is one of the biggest exercise myths.
The truth of the matter is that developing six-pack abs is extremely difficult, and your best shot is to lose body fat through:
1. Regular cardio exercise
2. Strength Training for the ENTIRE BODY (not just the abs)
3. A healthy, low-calorie diet
If you're one of the many who have lost body fat and still don't have the abs of your dreams, you can probably blame it on genes because many of us just aren't built to develop super toned abdominals - even with a near perfect exercise program and diet.
This certainly doesn't mean that you should give up - just make sure that your goals are realistic and attainable.
