I am not saying there aren’t any athletic people who weight over 220lbs. I am just saying that the vast majority of humans are not 6’2” so those who weight 220lbs+ Are mostly overweight than athletic
As one person I worked with in the health area BMI isn't that helpful when it comes to large guys 6 2 and up who do sports - the example they gave was the props in a premiership rugby team.
BMI is a pretty poor indicator. Raw bodyfat is probably the best measure of "obese or not."
Someone at 15% bodyfat and 6 feet, 1 inches tall can easily hit 220 pounds, if they have high muscle mass.
As another commenter pointed out, this isn't even considering the weight of clothing and carried items. My backpack usually weighs at least 15 pounds, sometimes up to 25. Clothes adds another, what, 3, 5, maybe even 8 pounds if I'm wearing boots?
