Excerpt:
A lot of people are told they can expect to lose up to two pounds of fat each week with a program of regular aerobic exercise.
Some do. But a lot of people fail to see anything in the way of meaningful results, even after months of trying.
It's easy to think the problem lies with you. Is it because your metabolism is slow? Are you getting older and burning calories at a slower rate? Is it in your genes? You stick to the program, and still you don't lose any weight.
What's going on?
If you're not losing weight, it's probably not your age, your metabolism, or your genetics that are causing the problem. It's simply the fact that conventional aerobic exercise programs are not a particularly effective way to drop the pounds.
