Let's get moving!
Population studies have found a correlation between regular aerobic exercise and decreased risk of at least 35 different diseases. But what have interventional trials proven in terms of cause and effect? Randomized controlled trials of older adults have demonstrated that physical activity can improve muscle mass, strength, balance, and mobility; decrease the risk of falls and potential fractures; and help minimize bone loss.
Exercise may also improve cognition, enhance mood, successfully treat depression (as well as the antidepressant drug Zoloft), improve erectile function in men, and generally improve quality of life. The evidence supporting the overall health benefits of physical activity are overwhelming. Exercise is medicine.
Exercise is such powerful medicine that a single session can improve insulin sensitivity for up to 17 hours. Researchers at Stanford and the London School found that exercise may work as well as drugs for patients with coronary heart disease, heart failure, and pre-diabetes, and even better than some medications for stroke. Of course, it doesn’t mean you can’t do both.
Exercise is so important that not walking an hour a day is considered a “high-risk” behavior.

* Before starting any vigorous physical activity, check with your doctor. If you are prone to feeling dizzy or have chronic unstable health conditions, it is always best to consult with your medical team before starting any new exercise routines.
