Gilad: It always seems that the area you want to lose weight from the most is the area you lose the weight from last.
This is very common problem for many people although the problem area varies from person to person.
Some hold the extra weight in the abdominals, a common problem for men, while woman tend to hold extra weight in the hips and thighs. Regardless of your specific problem area the solution is simple: PERSISTENCE! Look at what you have accomplished already as your motivation and let it lead you into conquering that last stubborn area.
You can also spend a little extra time on specific exercises to target your problem area.
In the case of the abdominals I recommend my "Lord Of The Abs" DVD series. This is a "Core Cross Training Program" that will get your entire body in shape while focusing on the core.
I am a firm believer that if you stick to your fitness program and eat healthy that you will be able to accomplish your goals and even get rid of that last bit of stubborn fat.
