For Men

Body Fat Assessment from waist minus wrist girth measurements.

1. Waist measurement at belly button (inches) = ______.

2. Wrist measurement at front of bones where wrist bends (inches) = ______.

3. Body Weight (in lbs.) = ______.

Plug in the numbers as indicated below.

______ - _____ = ________.

1. Waist 2. Wrist Difference #

Plug _________ and ___________ = into chart (see Table 6.5) to obtain __________.

3. Bodyweight Difference # % Body Fat.

Example: John weighs 160 pounds, and his waist and wrist girth measurements are 36.5 and 7.5 inches, respectively.

Waist girth = 36.5 inches

Wrist girth = 7.5 inches

Difference 29.0 inches

Body weight = 160.0 lbs.

1. Waist measurement at belly button (inches) = 36.5.

2. Wrist measurement at front of bones where wrist bends (inches) = 7.5.

3. Body Weight (in lbs.) =160.

Plug in the numbers as indicated below.

36.5 - 7.5 = 29.

1. Waist 2. Wrist Difference #

Plug 160 and 29 = into chart (see Table 6.5) to obtain 22.

3. Bodyweight Difference # % Body Fat.

For Women

Body Fat Assessment according to girth measurements (centimeters).

A. Upper Arm (1/2 way between shoulder and elbow) = _______cm. = ____________.

(Arm Conversion).

B. Age = _____ = _________.

(Constant B)

C. Hip (at largest circumference) = ___________cm. = ____________.

(Hip Conversion)

D. Wrist (in front of bones where wrist bends) = ________cm. = ___________.

Body Density (BD) = A - B -C + D

BD = ________ - _____ - ___________ + _________ = ___________.

Insert A, B, C, and D in above boxes to obtain Body Density.

% Body Fat equation = (495 ÷ BD) – 450 = % Body Fat.

Example For Women.

Body Fat Assessment according to girth measurements (centimeters).

A. Upper Arm (1/2 way between shoulder and elbow) = 27 cm. = 1.0813.

(Arm Conversion).

B. Age = 20 = .0102.

(Constant B)

C. Hip (at largest circumference) = 99.5 cm. = .1206

(Hip Conversion)

D. Wrist (in front of bones where wrist bends) = 15.4 cm. = .0971.

Body Density (BD) = A - B -C + D

BD = 1.0813- .0102- .1206 + .0971 = 1.0476

A. B. C. D. (Body Density)

% Body Fat equation

(495 ÷ 1.0476) - 450 = 22.5.

Thus Clients Body Fat % is 22.5%.
