"Adult obesity rates increased in 23 states and did not decrease in a single state in the past year, according to
F as in Fat: How Obesity Policies Are Failing in America 2009, a report released today by the Trust for America's Health (TFAH) and the Robert Wood Johnson Foundation (RWJF)"
With adult activity levels ranging from 16.3% (Minnesota) to 31.8% (Mississippi) no one should be surprised that obesity levels are continuing to rise. (2009 Trust for America's Health)
What makes the problem worse, at least from my perspective, is the overwhelming amount of misinformation about how to loose or even maintain weight properly. From FitFlops "the flip-flop with the gym built in" to the often repeated weight loss advice that says exercising at the aerobic training zone is the best way to loose fat, even when someone is sincere about wanting to loose body fat, coming by accurate knowledge about how to do so is difficult if not impossible for the average person.
To be fair, if you are completely inactive, exercising in the "aerobic" training zone will most likely provide you with some benefit, but then again, so will any activity.
Exercise for fat loss is not all that complicated. The harder you work the more you get out of you time exercising. (Assuming, proper form, appropriate weight, proper rest periods, etc.) It is all those little details that a knowledgeable, experienced, and educated professional can teach you. A good trainer will most likely be able to teach you new exercises, new ways to do old exercises, and how to design your workouts to make the most of your time in the gym.
There is no such thing as a quick fix. It takes a long time to get fat and it takes a long time to loose it.
What it comes down to is simple, when you exercise you have to put effort into it. If it is not hard then you are probably not doing it right.
