The risk for various health problems increases with age. But there are steps people can take to help minimize these risks, and exercise seems to be one of those steps.

The benefits to exercising can be immediate. More energy and better sleep are two. While fitness has immediate effects on the body now, fitness as a young adult can also impact the body down the line, particularly where the brain is concerned.

There are many benefits to being physically active. For older women, one of those benefits may run as deep as the bones.

Mild cognitive impairment causes problems with memory, language and thinking. It can also put people at a greater risk for developing Alzheimer's.  For patients with mild cognitive impairment (MCI), exercising may offer some protection for the mind.
