Sounds like a kind of weird question right? Doesn't everyone want that nice looking stomach? It is a great goal to have, but maybe not ideal. A slim waistline is fine, but the six pack look might be taking it too far. To have visible abs like that, women typically need to drop down to 16% body fat or less. That is VERY low and trying to get there can have serious side effects. Many women will overexercise and under eat to try to reach this goal. The combination of too much exercise and not enough caloric intake leads to amenorrhea (absence of a menstrual period). You can not starve yourself into shape! Chronic amenorrhea can lead to infertility, high cholesterol, osteoporosis, and premature aging. Don't sacrifice your health for short term goals. I highly encourage you to exercise as often as you can, but be smart about it. Listen to your body, it's ok to have a rest day! In fact, it is absolutely crucial to have rest days so you can continue to improve. And don't starve yourself. Instead of cutting your calories down to such a dangerous level, concentrate on putting more nutritious food into your body. I promise your body will look and feel much better if you give it the vitamins and nutrients it needs, rather than depriving it of calories.
