"More isn't always better," said study researcher Paul Williams, staff scientist at the Lawrence Berkeley National Laboratory in Berkeley, Calif.
Williams tracked nearly 2,400 heart attack survivors from his long-term study of runners and walkers for about 10 years. In general, increased exercise reduced their risk of dying from a heart attack by up to 65 percent, he said.
But running more than 30 miles a week or walking beyond 46 miles weekly had the opposite effect, more than doubling heart attack risk, the study found.
Over the decade-long study, 526 people died, nearly three-quarters because of heart attacks and heart disease.
Because the study was limited to heart attack survivors, Williams can't say if the findings would apply to healthy adults who exercise intensively.

Does anyone recall the old John Wayne commercials where he was speaking on behalf of the Presidents Program for Physical fitness(or something like that)? He said "Just do anything;run,walk,swim,ride a bike,or whatever".All spoken after he was down to less than one lung.
Lazy people should not exercise.
Common sense dictates, do everything in moderation. And most importantly, allow No One to push you. Your body gives you warning signals (pain, dizziness, fatigue), usually way in advance of a serious problem. When it happens, heed the warning signals. To continue to push yourself is the sure sign of a lack of intelligence. Common sense should be the rule and guide post, not some doctor nor others, that will still be here when you're dead from excess because you took their advice versus listening to your own body.
