Free miracle cure! Reduce your risk of heart disease, stroke, diabetes and cancer by up to 50%! If there was a pill with these sort of success rates people would be queuing up to buy them. But why stand in a queue? Just walk around briskly and take some exercise and that’s the sort of health benefits you can expect.
As a bonus it can also improve your sleep quality, give you more energy and reduce the risk of mental health diseases such as depression, dementia and Alzheimer’s.
And it doesn’t have to be pumping iron down the gym. Regular movement is just a important – so if you commute, walk quickly to the train or bus and keep adding those minutes up throughout the day. Sedentary jobs and lifestyles are a big killer.
You need a balance of regular movement as well as muscle gain (resistance training) and aerobic exercise – plenty of walking is good but you also need a couple of sessions of vigorous (i.e. make you breath hard) exercise for the biggest benefits.

- Thinning of shock-absorbing cartilage is a key feature of ageing but physical activity appears to reduce this thinning.

Whole-body vibration may be as effective as regular exercise – Kurzweil AI – 16-Mar-2017
WBV can mimic the muscle and bone health benefits of regular exercise — at least in mice.
When the machine vibrates, it transmits energy to your body, and your muscles contract and relax multiple times during each second.
Exercise and WBV enhanced muscle mass and insulin sensitivity in the genetically obese mice.
Heart repair – New Scientist – 8-Feb-2017
Exercise doesn’t just make your heart go faster – it might fix it too.
30 minutes running on a treadmill changed activity in hearts of mice.
Increased activity of genes involved in repairing DNA may help explain why exercise protects against heart disease.

Rising chronic inflammation is characteristic of aging and the failing immune system.
Less inflammation is a good thing when considering long-term health.
Just one session of moderate exercise can stimulate the immune system, producing an anti-inflammatory cellular response.
Research may contribute to developing new therapies for patients with chronic inflammatory conditions.

Exercise Differences Do Not Produce Longevity Differences in Identical Twins – Fight Aging! – 21-Dec-2016
Life expectancy and exercise are linked robustly in many data sets.
Accelerometers are cheap and ubiquitous so can use them to obtain actual rather than self-reported data on physical activity.
What if people who are more robust and would live longer regardless of exercise tend to exercise more?
Minimal exercise increases life expectancy of over-60s – Express – 3-Aug-2015
