Frequently Asked Questions
What is the Jackson-Pollock skinfold method?
The Jackson-Pollock method estimates body fat percentage by measuring skinfold thickness at specific body sites using calipers. The 3-site method is quicker, while the 7-site method is more accurate.
How do I take accurate skinfold measurements?
Pinch the skin and subcutaneous fat between thumb and forefinger, pull it away from the muscle, and apply the caliper about 1 cm below your fingers. Take each measurement twice and average. Measure on the right side of the body.
