A running back with less than 10% body fat would be considered overweight by BMI standards.
I had about 8% body fat.
I had a 30" waist and 44" chest.
I ran 5-10 miles a day, depending on the day.
And seriously lifted weights for 1 hour a day.
We had something called the Iron Man Club at school. Numerous lifts and running events. Some for raw strength, some for endurance, some for time.
For my weight class, I was the only person, my year, to place in all categories.
I had a friend in HS, 5 years later who said my name was still on the board, in a number of categories.
During my senior year, I had an injury that required me to go to the ER. I had a little oriental doctor, maybe 5'-6", who told me 185# was too heavy for my height and told me I should lose 15-20#.
I took of my shirt, which I wore oversized and told the doctor my body fat %, then asked him where he'd like me to lose the weight from.
Up until I hit 40, I could never buy a complete suit, always individual pieces, except if the place would cut out the seams of the pants and virtually remake the pants.
(I don't have that problem anymore.)
