This is true. I’m 5’9 171, run about 6 miles a week, can still bench 250 (I’m 61) wear 34 jeans and I show as overweight. I weighed exactly that when I was on an athletic scholarship and college, but had a 29 in waist and could press 290. My weight varies between 169 and 173, anything over 169 is overweight. My healthcare at work checks body fat percentage and mine is 12%.
It doesn’t take into account whether you have shoulders, or a slight build. Just for a comparison, most of the NFL will be between overweight and obese.
