That’s an accurate assessment.
However, I think that generalizing this topic in those terms isn’t the best way to go about it.
Instead, we can elaborate on losing fat AND strength training.
When we talk about fat loss, something that is often overlooked is that our bodies burn fat in the opposite order that it is stored. Most people tend to store fat in 3 areas. Butt, Waist, Chest. Women tend to store fat in their chests and buttocks more (proportionately) compared to men. Men store fat in the “gut” most often. Those who are overfat may have relatively lean bodies except for “problem areas.” Just knowing that simple fact (that fat is lost in the opposite order it was gained) can be enough for some clients to stay motivated to keep exercising and eating right so that they get the results that they are looking for.
We know that strength training is a great way to burn fat while maintaining lean muscle mass. Visit this website for a good article that covers different aspects of strength training. I think this information is valuable to the layman. http://www.naturalnews.com/011285.html
Depending on the needs of the client, a good personal trainer can develop an appropriate strength training program that can help to encourage functional movement in everyday life while working to achieve those goals for fat loss and muscle definition.
Another thing to keep in mind is diet. Diets high in fat, generally, are not doing much to help you on your way to gaining muscle definition. As a blanket statement, following your RDAs is a great way to make sure you’re getting a good, balanced diet. The best thing you can do for your body is to put good, quality nutrients in, while maintaining appropriate portion sizes, regardless of physical activity.
Also, keep in mind that fitness is not measured by how “cut” you are. The appearance of fitness (shredded like a julienned salad) is not necessarily ideal. There can be a lot going on inside your body that might make a “shredded” person just as unhealthy as someone who is overweight/overfat. The opposite may also be true.
I think that muscle definition is a great goal to work toward as long as it is secondary to overall health and fitness.
