BMI is really misleading. Honestly, I think that it's outdated.

BMI doesn’t take a person’s overall muscle mass or body fat percentage into consideration. It really makes no distinction between weight gained from fat stores and weight gained from lean tissue. Instead, it lumps everyone of a certain height together into one group, regardless of their activity levels, genetics, body composition, medical history, frame size and age. Height is just one variant here that determines how much you “should” weigh.

Keep in mind that BMI was never intended to comment on our health. It was originally just made for the sake of gathering census data.

So don't take your BMI too seriously! It's a really basic overview of an incredibly complex medical issue.
