Do you use BMI as part of your documentation? Why/why not?

Curious to see what other trainers think about BMI and including it as part of tracking client progress.

Personally, I don't use it because of the mathematical scaling issue. The altered formula proposed by Dr. Trefethen in 2013 is much better but I still don't think it's a good metric to track progress with.

I use body fat percentage and general landmark measurements alongside 3 rep maximums or other fitness tests. I think it's easier for most people to grasp changes in pounds of body fat as opposed to the BMI ratio.

But like I said, I'm curious about how other trainers do things and I'd love to hear from a different perspective.
