well I did it yesterday.  I fell while hiking onto a straight arm and tore the shit out of my shoulder.  can’t lift my arm to get a coffee mug out of the cupboard.  I’m all slinged up, but still managed…weighted lunges, light deadlifts, toes2bar, trisep pushdows, cable curls, seated cable rows.  1 month easy peasy, 3 months until I can be strong again.  If it isn’t somewhat better in a week I’ll hit the Doc.
