I've heard time and time again - running is bad for your joints. But lately I've been hearing something totally opposite, that running can actually improve joint health...So which is it? Supporters of the first school of thought argue that all the pounding eventually wears away at your joints, supporters of the second school of thought argue that running strengthens the muscles, tendons and ligaments that support your joints and stimulates the synovial fluid that lubricates.
So which is it? Which doctors and "scientific evidence" (that everyone inevitably seems to have to back up their argument) do I believe?
