| Anything below 7 depending on genetics is practically impossible to maintain. When you see body builders in competition and they're at 3-5 % they stay like that for no more than a week or two at a time, they have to seriously dehydrate themselves to look like that. Same for the super lean people you see on magazine covers. when they're not working the add fat you should see some of the bodybuilders during the off season, huge pot bellies. |
