I don't think anyone can argue with the idea that exercise is good for you, no matter what your age, and importantly, that it's never too late to start. I started this article with a quote and would like to finish with one as well. It's by Dr. George Sheehan. Dr. Sheehan was a cardiologist, who, in the 1970s, at the age of 45, decided to turn around his health and his life. He caught the running bug and started to train, compete, and run marathons. He quickly became an expert on the subject and started writing weekly fitness columns in local newspapers. He was medical editor for Runner's World magazine for 25 years; he counseled his patients on the virtues of exercise; and he lectured internationally. He wrote eight books about running, fitness, and health, and he played a key role in promoting the running boom of the 1970s. He was philosophical about winning, losing, suffering, meditation, training, and working through pain, and he would quote the likes of William James for inspiration. In 1986, Dr. Sheehan was diagnosed with prostate cancer. Unfortunately, the cancer had spread to his bones by the time he was diagnosed. He hung on courageously for seven more years, running and competing up until the end of his life. He died in 1993, just four days short of his 75th birthday. Dr. Sheehan had the following to say about his experience with running and with life. "No matter how old I get, the race remains one of life's most rewarding experiences. My times become slower and slower, but the experience of the race is unchanged: each race a drama, each race a challenge, each race stretching me in one way or another, and each race telling me more about myself and others."
Resistance exercise (weight lifting, calisthenics): To promote and maintain health and physical independence, older adults will benefit from performing activities that maintain or increase muscular strength and endurance for a minimum of two days each week. It is recommended that eight to 10 exercises be performed on two or more nonconsecutive days per week using the major muscle groups.
