Walking is much better than not moving at all, but walking doesn˙t fix all the health
issues.
For walking to be really beneficial you need to do it often, several times a week,
preferably every day, and for an hour at a brisk pace that get your hearth and breath
going.
But walking doesn˙t put much strain on the bones, so you might still get osteoporosis
(weak bones) when you get older.
You need to do something more than just walking.
Running is one possibility, which is also the next level for cardiovascular health.
Strength training at the gym, with weights or machines, are also efficient for counteracting osteoporosis, and maintaining muscle health and strength.
Even 20-30 jumps per day, such as jumping off a small 8-inch step or doing squat
jumps, can have a positive effect on bone strength.
Then there is stretching or yoga to reduce stiffness by age.
Another important thing to train as we age is balance, to reduce the risk to fall.
The balance deteriorates with age, almost unnoticeable, until it becomes very noticeable.
The table below show how long people typically can stand on one leg with closed eyes at
different ages, without losing balance[1].
Close your eyes, then raise one leg and start the timer.
One opportunity to train this is when you˙re brushing your teeth. Try doing it standing on
one leg, and close your eyes.
