Exercise increases neural density and makes you smarter.

Exercise causes your brain to adapt. This improves brain function, and it doesn’t matter what your age. Researchers have shown children who exercise (games, play etc) have a greater mass of brain matter. This makes them smarter. This becomes more relevant the older you get  – exercise will prevent the loss of brain function that is associated with dementia.

Just 30 minutes of exercise has benefits for the brain.

Exercise is a medicine that becomes more important with age.

 

The human body never loses the ability to adapt – whatever your age exercise will stimulate your body. Exercise achieves much more than strength adaptations though. It improves proprioception (balance, stability), joint stability, improves range of movement, functional capacity – but exercise is also medicine. It stimulates the body to heal.
