12.9% is underweight and unhealthy. At 209 lb. you would have to be well over 7 foot tall to be at 12.9%.
LOL- not even close. 7ft tall/209lbs is an issue. I go about 6-2.
When i trained for the Olympics i was 5.6% at 190lbs. Under 5% is considered risky for some people.
I’m much rather be 12.9% than 21.9%
