I’ve never been a big fan of bioelectrical impedance analysis (BIA) for body composition assessments, particularly for athletes. Jeff Stout and his colleagues at the University of Nebraska-Lincoln produced several studies years ago that revealed the BIA procedure was flawed in assessing body fat levels in lean, muscular people.

Even compared to a basic 3-site skinfold test, BIA couldn’t remain consistent or accurate.

I really want to add some good muscle size, but I just don’t have the time to train for hours each day and the eating you guys do just won’t fit in my schedule. Is there a less time consuming and less burdensome way to build muscle?

A recent body composition study utilized bioelectrical impedance analysis on bodybuilders and powerlifters and failed to perform as accurately as a traditional 5-site skinfold assessment.

For an accurate, economical body fat assessment stick with the skinfold caliper test done by an experienced, certified trainer at your local gym.

I read your report on the error margin in bioimpedance devices and I wanted to know if you were referring to the average person or athletes?
