There is no way to target weight loss to a specific area of the body because your body decides where it wants to put on weight and where it wants to take it off (genetics). The midsection is a common “problem” area for many people (mostly us females).
The best way to lose fat is through exercise (both strength training & cardiovascular) & diet. It is important to do a variety of abdominal exercises (e.g. crunches, reverse crunches, plank, etc.) to keep your core strong, but until that excess fat is gone, you will not see the muscle definition. So if you’re not doing your “cardio” and eating right, crunches are not going to help get the 6-pack some of you are hoping for.
And speaking of “6-packs”, you need to know that as a woman, achieving a “washboard stomach” is sometimes difficult. Due to genetics and our hormonal systems, women naturally carry more fat around our hip & abdominal areas. For a woman to have a visible 6-pack, she most likely has a body fat percentage below 15%, a number that is challenging to maintain on a day-to-day basis.
A combination of regular cardio exercise (at a challenging intensity, that is!) Boot camp training and a healthy diet is your ultimate bet!
