The Army website says all applicants should have a body mass index of 18-28. Apparantly the body mass index is a flawed system that does not provide accurate results for people with athletic build. My body mass index is 29, I am muscular and take regular exercise. I regularly run 5 miles with ease and do all sorts of weights yet I am 1 over what the army states to be acceptable body mass index. Will this prevent me applying?
