Is Too Much Exercise Bad For Your Heart?

Since the death of ultrarunner Micah True, there has been a good bit of news making the rounds debating on how much exercise is too much exercise. Some have said that more than 25 miles of running per week is too much. Others have said that more exercise is always better. Still others are still sitting on the couch and using these headlines as an excuse to not get up and exercise.

The full formula on what is too much is probably very complicated. It is probably different for every person, and probably different for a person at different stages of his or her life.

My two cents: Get up and exercise, chronic over exercise might be bad for the heart, however a sedentary lifestyle is bad for health.

If you are worried about the health effects of over exercising, don't run 5 marathons a year, but do run for fitness and fun. If you are running less than 20 miles per week, you have nothing to worry about. If you spend 8 hours per day sitting, you have a lot to worry about.

Meanwhile, I will leave the search for the facts on this issue to the exercise scientists and cardiologists while I train for my trail half marathon and olympic triathlon next year.

How about you? Do you plan to change your training based on these reports? Comment below.
