Strength training remains important as we age. It's critical to build up your muscle mass, which will help you fight off disease and prevent falls.
Beginning a new fitness program comes with great benefits at any age. An inspiring example of this Olga Kotella. She worked as a teacher, raised her family and retired at age 65 ... and what an amazing retirement! At the age of 77 she began training in track and field and went on to earn 37 world records and win 750 gold medals in nonagenarian track-and-field events around the world by the time she turned 95! Her story is inspiring, and that is only part of her legacy.
Concerns about our ability to stay mentally sharp increase as we age -- two interesting studies provide information that should help alleviate those fears! In 1990, test subjects between the ages of seventy and ninety were questioned about their levels of physical activity, with a follow-up that was conducted a decade later.
