You are right, BMI will not be accurate for a weightlifter. It will overestimate body fat.
For body fat calculations, the skinfold method is probably the most common one used and would be more accurate than BMI for someone with a significant amount of muscle. You would have to find a personal trainer who is experienced in taking skinfold measurements and calculating body fat using this method.
A less common method for determining body fat composition is hydrostatic weighing. It is considered to be one of the most accurate methods, but it may be difficult to find a place that does it.
There are also smart scales out now that measure body fat, etc., but they are apparently not very accurate.
I lift weights but have a bmi score of 24.7 currently. So weight lifting hasn’t pushed me into the overweight range.
