When measuring, the subject stands naturally, bending his right upper arm forward first, then slowly straightening his forearm and loosening his fist. The measurer wraps the tape measure around the biceps brachii of the right upper arm, and the measured value is the arm circumference. The measured position is the triceps brachii part of the upper arm.

Measurement process of arm circumference:

1. Relax your arms and put the tape measure on the biceps brachii.

2. Bend the forearm hard and measure the top of biceps brachii with a tape measure.

Simply put, the measurement position of the arm circumference is as follows:

Measure the triceps brachii part of the upper arm with a soft tape measure, that is, the part where the shoulders in the middle of the upper arm naturally droop, and measure it at a distance of one centimeter from the shoulders.

Standard measurement

According to the "measurements" of the curvy figure of ordinary women in China, China bodybuilding experts combined with the influence of fitness exercise on human body shape, summed up the calculation method of the standard measurements of women:

Chest circumference = height ×0.535, waist circumference = height ×0.365 and hip circumference = height ×0.565. According to the statistical results, the "measurements" are less than 5 cm, indicating that they are too slim (thin); More than 5 cm indicates that it is too plump (overweight).

Professional female models are measured differently. Due to professional needs, their measurement standards have a certain gap with the normal standards.

According to the national characteristics of our country, the standard of measurements is generally chest circumference of 84cm, waist circumference of 6 1cm and hip circumference of 90cm.
