Yes...if you don't want to get fat, to a periods of each...most bodybuilders have nothing else to worry about through the winter, so can just get as big as they want.

Big shoulders, small waist is the whole aim! Small legs no, but small waist gives you that V-taper...check out Vince Gironda, Mohammed Makkawy and Larry Scott.
Larry Scott, by the way, had a bad body structure in BB terms, narrow shoulders and wide waist, but with effort and determination he looked amazing!
