Calcium alone cannot build bone unless it is combined with a consistent exercise program. Exercise is key in staving off osteoporosis. Walking and other weight-bearing exercises strengthen the bones, but exercise also stimulates the cells to make new bone.
Not only does it help to keep bones strong, it strengthens the muscles, which gives the joints more support, and keeps you limber, which can help prevent falls. What’s more, exercise does not have to be strenuous to stop or reverse bone loss. Two studies have found that older adults who walked at least 20 to 30 minutes daily had much denser bones than sedentary adults.
