I don't consider "skinny" an ideal by any stretch of the imagination. I do consider "good body composition" - some happily moderate combination of decent muscle mass and low bodyfat - an ideal. I think it's obvious that a vocal portion of the posters here idealize skinniness regardless of physical fitness. Different strokes. Right now I'm about 145 lbs at 5'9". That's pretty skinny by most healthy standards, but positively zaftig by this forum's standards. The current realities of my metabolism, activity level, diet, and nagging injuries make it very difficult for me to gain weight while maintaining a decent body composition.
