We are created to move. The benefits of exercise transfer to all areas of life. I guess one of the most underappreciated form of advantage is the cognitive advantages: people who exercise more learn faster and remember better.
Above all it is not even that difficult: we just need to reduce the passive time and substitute it with standing up or walking for example.
The 10 000 steps a day is a worthy goal. Even if you cannot make it to the 10 000 try 7 000 at first, it’s gonna transform your life in the long run, not just your body, but your mind as well.
Over time, exercise energizes. Exercise let’s us to rewire our thoughts and emotions into a more positive state as well.
Health is based on movement, nutrition and sleep. If you have enough of all these, you are likely to live a healthy life. Then there are exceptions to both directions. Those who exercise gain the health advantage, those who do not throw the advantage away.
