It is what it is, but I think we can solve both of these problems. I have trained and tested over a 1000 trainers on these body fat methods and when they graduate from NPTI they are pretty good at it, but even with that training there is more variability than one would like. But to use these formulas you need a trainer to take the measurements on you, and if you don’t get the same person there is likely to be reasonable variation in the result. Checking body fat should be like checking the scale, you can check in daily or at least weekly to see your progress if you want. There is nothing inherently wrong with these formulas, it is just that they are very inconvenient to use.

No formula uses them all, Parrillo uses all of them except for the midaxillary site. There are 10 standardized body fat pinch sites. This formula tends to predict a body fat percentage in between the Durnin & Womersley and the Jackson/Pollock formulas. Again, you do the same deal – add up your total and look on a chart to find your body fat. This involves taking body fat at 9 sites: chest, abdominal, thigh, bicep, tricep, subscapular, suprailiac, lower back, and calf. This was created by the bodybuilding coach John Parrillo and he wanted a formula that was specific to bodybuilders and fitness oriented people. The third formula is the Parrillo formula. In my experience this formula tends to underestimate one’s body fat. That involves taking body fat at 7 sites: chest, abdomen, thigh, tricep, subscapular, suprailiac, midaxillary use another formula and it will give you a body fat percentage. There are actually 3 versions of this but they all derive from the main one, the Jackson/Pollock 7. In my experience this formula tends to overestimate one’s body fat especially for fit people.Īnother popular method is the Jackson/Pollock Method. In my experience this is the most popular method used. You add the total of the four sites together, use a fancy formula, and it spits out your body fat percentage. There is the Durnin & Womersley method, which involves taking body fat at 4 sites: Bicep, Tricep, Subscapula, and Suprailiac. There are 3 popular body fat formulas that trainers currently use. NPTI Director and Instructor, Tim Henriques, believes that he has solved both of these issues, and has created a more accurate formula as a replacement. There is huge inter-tester variability when it comes to the results.You need a trainer (or someone that knows what they are doing) because you can’t reach the sites yourself.Suprailiac: diagonal fold parallel and superior to the iliac crest.There are 2 very annoying issues that arise when taking body fat using the skinfold calipers.Tricep: vertical fold at the midpoint of the posterior side of tricep between shoulder and elbow with arm relaxed at the side.Thigh: midpoint of the anterior side of the upper leg between the patella and top of thigh.Abdominal: vertical fold 2cm to the right of the navel.Chest: diagonal fold half the distance between anterior axillary line and the nipple.Retake each site in order to obtain accurate readings. Wait 1 to 2 seconds after releasing caliber, record closest 0.5mm.

When skin fold is pinched, the practitioner should be taking reading at the middle of the pinched skin, not apex or base. The participant must relax the muscle group that is being assessed. Caliber needs to be perpendicular to the site analyzed. Measurements are taken on the right side of body. 3-Site Skinfold (Jackson & Pollock) Protocol PurposeĮstimate body fat % based on measurements of subcutaneous fat.
