are you doing your own prep or are you working with someone?  

working with someone that has competed before...he told me to just water load since i do not have a lot of body fat

if you're working with someone then i would trust them seeing as they have been there before.  if your bf is low and you are very lean then the person you're working with is probably pretty knowledgeable
