Exercise...what NOT to do

So if you read my earlier post you know that I am working on my "total health and fitness." It is going awesome. I feel great and like mentioned before I can fit back into clothes that had somehow shrunk...well now I have too. Anyway so I'm learning all these new exercises. I'm working my body in ways I didn't know it worked in. I have also learned moves that I shouldn't do. I'm posting a link to this video so you to can see what NOT to do.
