This video shows Dr. Evan Matthews explaining how to perform a body composition assessment to estimate body fat percentage using skinfolds. This is a common field test used in fitness centers and with athletes and the general population. This video starts by going over general tips and guidelines, then moves to how to perform the most common seven sites, then how to use the skin fold measurements to calculate body fat percentage (the rest of the tissue is lean tissue mass).

Male Body Density Equation (ACSM’s Guidelines for Exercise Testing and Prescription)
Body Density = 1.112 – (0.00043499 x sum of skinfolds) +
(0.00000055 x square of the sum of skinfold sites) – (0.00028826 x age)
Female Body Density Equation (ACSM’s Guidelines for Exercise Testing and Prescription)
Body Density = 1.097 – (0.00046971 x sum of skinfolds) +
(0.00000056 x square of the sum of skinfold sites) – (0.00012828 x age)
Siri Equation to go from body density to body fat percentage
Total Body Fat % = (495 / Body Density) – 450

Included in the 6-Pack Shredded Kit is a free body fat caliper. For those of you who have never used one before, James Grage explains how calipers work and provides a demonstration of a body fat measurement.
