Exercising multiple times a week may help strengthen your bones. As women get older, their bones get weaker but a new study has found that regular, light exercise may be the key to good bone health. “[The study]  found that women who exercised consistently every week experienced bone loss, but the reduction was significantly less than a control group that didn’t exercise regularly. In regular exercisers, bone density decreased by 1.5% in the spine and 5.7% in the hip over 16 years. Among controls, bone density in the spine and hips declined by 5.8% and 9.7%, respectively.” The study found that exercising twice a week was necessary and any less would be ineffective.
