I have one more question... how do I know how much weight to use?? I have never done any weight lifting before, also do I need someone around when doing them normally no one is home/ awake when I am (I work overnights) so I need to do exersices that are safe without supervision
broke down and bought the book night before but its not really clear on either (in fact the book was about as clear as mud and I normally don't get confused.. )
