If you believe in the BMI here is the answer for a man 5'10" and 180lbs: http://www.cdc.gov/healthyweight/as.../results_overweight.html?pounds=180&inches=70
Say's that is overweight.
I think the BMI is 100% totally a crock of SH*T, and so does pretty much everyone else I work with. Almost everyone, even the guys with a good build and a 6 pack is close to or is overweight according to the BMI, unless you're one of those tall lanky people you're fat.
According to that ^^ I'm obese and : For your height, a normal weight range would be from 144 to 194 pounds.
I would look like an anorexic bean pole at 190lbs, let alone 144. lol hahaha
I stopped looking at a scale long ago. It's how fit I am relative to my activites (like Caboose said, compete near the top %) and what you look like in the mirror.
I disagree with the whole weak mind comment.
