For those living with (>200 million Americans) or at risk for osteoporosis (see all aging women and men), physical activity is important. Regardless of what you may have been previously told by physicians or others, physical activity is necessary to provide stress to your bones which helps to promote strength and slow the breakdown of bone.
Osteoporosis can be classified as a chronic disease and as such is necessary to manage aggressively. The benefits of physical activity can include: improved bone density, strength, endurance and flexibility. Secondary benefits of physical activity also include reducing the risk for other chronic illnesses such as diabetes, heart disease and stroke.
The definition of physical activity is rather broad, but the most important item to keep in mind relative to osteoporosis is a weight bearing activity that places some amount of stress/strain through the bones. Exercises such swimming and cycling are great, but not as helpful relative to this condition. Pick an activity you enjoy and even consider including a partner to help with the motivation aspect.
Exercise has been also shown to not only improve physical but mental health as well. Now is the time to be active for your health. Do not wait until it deteriorates to the point of limited mobility.
