A few months back I wrote an article about the amount of exercise necessary to maximise life expectancy. That article, based on observational studies, concluded that you could get 90% of the longevity enhancing benefits of exercise with just half an hour of moderate intensity walking per day, which is nice for those, like me, who aren’t even remotely interested in intense sporting activities. When the other boys were outside kicking a ball around, I was lying in my bed reading books, so any scientific evidence supporting that lifestyle makes me happy.
In an earlier article we debunked the claim that exercise will help you lose weight. What about whether exercise will help you live longer? Now, don’t get me wrong, I am certainly not anti-exercise. There are lots of studies showing that exercise has many and varied health benefits, from improving muscle strength and balance, to decreasing the risk of fractures and delaying the onset of dementia. But will it help you live longer? And if it does, how much exercise should you be getting to maximize longevity? Are the famous ”10,000 steps a day” and ”half an hour a day” recommendations enough or should you be doing more than that?
