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.
