“Most people are familiar with many of the benefits of exercise, such as improving muscle strength and endurance, reducing the risk for heart disease and stroke, and preventing obesity. Perhaps not as well understood is the importance of regular physical activity in building and maintaining healthy bones. Inactivity causes loss of bone!

Aging, along with certain diseases and medications, can cause bones to become very weak and fragile over time — a condition called osteoporosis. It often occurs in women after menopause, and in men in older age. This bone-thinning disease puts people at a greater risk for broken bones, which can seriously limit mobility and independence. We also tend to lose muscle as we age — a condition called sarcopenia. People who develop osteoporosis or sarcopenia are considered frail: more likely to fall and more likely to break a bone.”
