According to a new study, too much exercise can kill you.

While regular, moderate exercise is good for you, too much exercise can hurt your heart and lead to a premature death.

Researchers say running too fast, too far and for too many years can end up causing your heart to stretch, tear and scar.

The study results suggest that if you want to exercise daily, you should limit the workouts to 30 to 50 minutes per day.
