Standard BMI categories tend to misclassify muscular people as overweight. For men with an athletic build, this uses research-adjusted BMI cut-offs (Nikolaidis et al., 2025) instead of the standard WHO ones. No equally validated adjustment exists for women yet, so female results always use the standard WHO cut-offs regardless of this choice.
