When you pound the pavement and stess your bones...they spring back stronger!

A study showed runners were half as likely to suffer from knee osteoarthritis compared with walkers. Surprised? Every time you pound the pavement, you stress your bones and cartilage, just like your muscles, causing them to spring back stronger, explains Janet Hamilton, CSCS, an exercise physiologist with Running Strong in Atlanta. Low-impact exercises like walking, or even spinning or swimming, don't have that same bone-building benefit. This was the conclusion from a Medicine & Science in Sports & Exercise study of nearly 100,000 runners and walkers.
