Study suggests you can run too much

As more and more studies show that short bursts of intense exercise are best for getting you into shape, you might wonder if there’s a limit to how hard you can work and still be healthy.

A new study from the Journal of the American College of Cardiology shows that joggers who run at a vigorous pace — though not at their peak effort — are likely to live longer than those who run at a really strenuous pace.

This doesn’t mean that not exercising at all is good, though: Of the study’s approximately 5,000 participants, the joggers (no matter how fast they ran) had better Body Mass Index, blood pressure and lower rates of diabetes than the sedentary non-joggers.

People who jogged at a decent pace for around 1 to 2.4 hours a week — spread out over three runs — had the best chance of living to old age, according to the study. The most intense runners — the ones who were working really hard for longer stretches — were as likely to die as those who didn’t run at all.
