Bone density is not just an issue for seniors. Osteoporosis — the result of low calcium in your bones — is considered a pediatric disease with geriatric effects, say researchers. Throughout life, walking helps avoid this condition by:

• Building bones. Bone mass develops during the teen years, with the “bone bank” set in your early 20s. Walking 30 minutes a day, five days a week encourages healthy bone growth and increases bone mineral reserves.

• Improving stability. Staying active helps maintain muscle strength, coordination, and balance — reducing the risk of falls and bone fractures.

• Leading to healthy choices. Youngsters who exercise are less likely to smoke or abuse alcohol — both of which increase osteoporosis risk.

Walking 30 minutes a day, five days a week can promote strong bones — throughout your lifetime.
