Today while I was doing sprint interbals, I messed my knee up.  When I walk it totally feels strained and painful. Does anyone/or any runners have any advice or idea of what might have happened?

i’ve noticed:

That if I take a break from working out, I’m so reluctant to get back into my routine.  A break constitutes 2 or more days.  I usually shoot for 6 days a week, with one day for rest.  I haven’t worked out since Friday and it sounds like hell.  I know at the end of it, I’ll remember when I love doing it six days a week.

Crossfit, killin’ it!
