Add stress systematically after running injury (DAY 3)

Why would you want to add stress?  We're not talking about psychological stress. We're not talking about the stress of a screaming baby or a boss yelling at you.  We're talking about stress on the tissues that will actually stimulate a healing response that makes them stronger later, just like working out.  If you're an injured runner who's getting back to running, you need to add stress systematically.  And that's what we're talking about today on the Doc On The Run Podcast.
