Revelations on fitness

This article reports on a study that found that some 10 percent of the people it studied "could never improve their fitness with exercise," and, more generally, that genetics plays a large role in determining how a person's body reacts to exercise and physical activity.

The general result isn't so surprising, but the apparent fact that some people hardly benefit from exercise at all is. It also seems to be the case that muscle size and muscle strength are largely independent — exercise will help some people increase their strength, but not the size of their muscles. In other words, you really can't judge a book by its cover.

It would be cool if Nike et al. would adjust their ad campaigns to reflect that.
