OH My God!!! The muscles in my legs are twitching and it has been over an hour since I left the gym.. I think I killed my legs this morning and they just don't know it. Like a chicken with it's head cut off running around.. I burned 937 calories in 45 minutes on the Arc trainer. I kept my heart rate between 150 - 170. I then walked around the track for about 20 minutes cooling down.. The laws passed that Ohio will be smoke free in bars, restaurants, Work places and Public Buildings..
