What a crock of shit. Weight to height and they think they can calculate BMI. That test is shit. You need to see a trainer to get an accurate reading of your BMI.
For example Travis Henry a stud running back for the Buffalo Bills is 5 ft 9. at 215 pounds. Benches 475 lbs and is fit as fuck. Enter his stats.
His BMI is: 31.7
Your weight is putting you at risk of health problems such as coronary artery disease, high blood pressure, diabetes, and stroke.

See a trainer for an accurate determination.
