Many systems in the body decline to an extent as we age. We don't run as fast, muscle mass declines if we don't do anything about it. The same is true for balance.

However, there is a great difference between having poorer balance than when you were younger and having poor balance. Some people often reverse a middle age decline in balance by being more active and working on balance when they're older.

The body is very adaptive. When we lift weights, our muscles get stronger. When we practice balance, our balance gets better. As little as 10 minutes a day can make a real difference.

We have measured 80 and 90 year olds who score 9/10 (great balance), and 40 year olds who score 4/10 (poor balance). We have also seen 85 year olds start at 2/10 and improve their balance to score 7/10. For more on how much balance can change no matter what your age, see these stories.

Users of ZIBRIO balance scales who also use the app can enter their balance score to find out how that score relates to other people their age.
