I stopped using scales 20 years ago. People used to slate me for it. I just look in the mirror naked, this is the best indication of the shape you're in. BMI is quite stupid, it can have people overweight. Even so a lot of the weight is lean muscle. The person can have low bodyfat, more lean muscle which weighs more then fat, yet according to BMI be overweight. It's an outdated process in my opinion.
