The Navy's Body Fat standard is nothing more than a scam to avoid paying pensions to people who are getting close to their 20 or 30 years in service or to reduce personel. It has nothing to do with your health, it is just for appearance. Look at some of the posts here. Some people are actually reducing their workouts because their muscle mass distorts their BMI score. This has been going on for years. We had a PO1 who was forced out because of BMI. Two months after he got out, he won a body building contest and qualified for the Mr. Universe competition.
