Study Says Exercise May Or May Not Matter

(CBS) - Is it possible that some people just don't respond to physical exercise? Researchers in Finland believe this may be the case.

They studied 175 adults and followed them for 21 weeks. According to their findings there were those who had no response and those who had excessive response to the exercise.

Genetics play a key role in exercise training but the researchers say genetics don't tell the whole story. In fact, they believe that diet, exercise, and the type of exercise play a role depending on who the person is.

The bottom line is that the study tells us more or less what we already know. Some of us do far better with exercise than others. Ultimately, this is not a big deal but what matters is that we are consistently trying to exercise and achieving those basic goals for a healthy heart and a long life.
