The whole article by Bonnie Liebman is found here, but the summary is below.

“Here are 10 ways inactivity can take a toll on your body:”

  1. Diabetes. Biochemists and physicians talk about the metabilic syndrome” that leads to type 2 diabetes, but it really should be called the inactivity syndrome.
  2. Cancer. Active people have 30-40% lower risk of colon cancer. Active women have less breast cancer.
  3. The Brain. Physically active people have lower risk, about 50% lower, for cognitive decline and dementia than inactive people.
  4. The Heart. Active people have much lower rish of heart attack and dying of heart disease.
  5. Stroke. Same goes for stroke.
  6. Muscles. Muscle atrophy is a serious problem for the elderly. The way to avoid it is through exercise.
  7. Bones. Osteoporosis is a major problem, much of which can be ameliorated through weight-bearing exercise.
  8. Mental health. Exercise is great for the psyche as well as the body.
  9. Weight. Exercise helps control body weight.
  10. Immune system. Regular exercise may boost the immune systme…unless you overdo it. “Marathon runners have a higher risk of colds after a race, because immune function goes down after a prolonged intense bout of exercise.” [My own comment on this is that the training is so valuable to boost the immune system that I’m not worried about the increased chance of catching a cold after a marathon.]

The article goes on to say that the benefits of exercise require that you work out at least 30 minutes a day [5-6 days per week], but 60-90 minutes is better for substantial weight loss. To build muscles and avoid bone loss, do strength training exercises at least twice per week.
