Study: Too much exercise can lead to death, especially for white men

Working out is good for your health, but it turns out too much exercise might kill you, especially if you are a white man.

Researchers in Chicago discovered very active white men are 86-percent more likely to experience a buildup of plaque.

This study involved more than 3,000 men and women of different races, followed for 25 years.

They found if a white man worked out for at least seven and a half hours a week, he was nearly twice as likely to suffer from heart disease.

Researchers did not see a spike in other participants.

They think high levels of exercise over time causes stress on the arteries.
