I apologize in advance if this has been posted already. John Berardi/Precision Nutrition just opened up his forum to non-customers a few days ago. This is what I am most impressed with so far: Access to the new Precision Nutrition Exercise Database with high resolution video demonstrations of over 450 exercises (each exercise from multiple camera angles). http://www.precisionnutrition.com/members/exercise.php I like the exrx.net site, but I think these videos rock. Not affiliated with them, just thought it was a great resource to share.
