Yes, I know. However, as an athlete who has had experience at various weights, I know what my waistline would be (and actually was) at various weights.
When I ran at least 10 miles per day at a brisk pace (trained with a D-1 track/cross-country team), lifted weights & swam daily, had very well developed six-pack abs, and a very healthy diet, I would have been classified as “overweight” by the BMI calculations. This shows how outdated the BMI figures are. Totally worthless.
And, please, do not get me on the subject of buying collared shirts as most manufacturers do not make my neck size–even the case when I had a 28" waistline.
