As a personal trainer for 15 years here in Las Vegas I have always performed body fat testing on my clients with calipers and have been fairly accurate. One of my clients had the stkyu scanner performed on her and the accuracy and ability to perform tests that I cannot is excellent. Areas like bone density, metabolic rate, exercise volume to access caloric intake and along with so much more and a 12 page detailed scan report. I highly recommend this test to anyone wanting an accurate assessment.
