I was reading the sticky about how to do a body comp test using calipers. It states that calipers are only accurate for up to 18% for men. I know I am more than 18% and I also know that BMI calculators are junk because they put me at 31.2% which I think is incorrect. What are other effective ways of measuring my BF? I would like to monitor it and track it's decline to see how well I am doing. I'm 75.5'' tall and weigh in at 253.
