Which is better for bones - walking or biking?

Answer 1

Cycling is generally accepted as better for bones. Cycling involved little to no impact at any point and is thus less likely to cause damage to the skeletal-muscular structure. Many leading medical professionals will suggest cycling to people going into retirement as you can cycle well into your 70's if your body is in proper shape. Cycling only becomes dangerous when one's sense of balance begins to degrade and reflexes become dull. A fall during cycling is obviously far more serious than a fall while walking.
