Sanchin, don't worry about the BMI, this was designed for everyday normal people who do not work with weights or exercise to become bigger and stronger.
My own BMI is around 29.51 and I am in very good shape. Could be better if I wasn't injured and taking a break but still in better shape then the majority of people.
If you took the BMI from any pro athlete they would all be considered possible candidates for a coffin.
