"I need to lose some weight" and "I wish I could slim down a little bit" are two things that I hear all to often in the gym. I myself have said these things but do others really now what they are asking for. Striving to be a Certified Strength and Conditioning Specialist (CSCS), I have looked into what this really entails, and most of it comes down to nutrition.
When most people say they want to "lose some weight" they think, "I'll just eat less". Just eating less is not the key. Cutting calories will help and you will lose weight but you are not going to lose just the weight you want to. You could lose some muscle mass in the process.
The other part of "losing weight" is "slimming down". Many times I have been asked, "what ab exercises can I do to get rid of this stomach"? Well the answer is really none. In order to shed those excess pounds around your mid-section, which undoubtedly most of us have, you need to try and do exercises that get the heart rate up and boost your metabolism.
What it all really comes down to is a proper diet and a good totaly body workout plan. If your not eating healthy or properly no matter what your goals are they are going to be very difficult to achieve and well concentrating on a certain body part isn't necessarily a bad thing, working that one part solely is and can cause a domino effect of injuries, aches and pains.
If you have any questions on nutrition I suggest visiting
www.mypyramid.gov it is a great site that is free and easy to use. With just a little bit of research on the internet you can always find workouts you are looking for as well.
