The vest line refers to a line with no excess fat in the abdomen and a sense of muscle. The abdomen is mainly composed of two parts, namely, abdominal muscle and external oblique muscle. The distance between these two muscles will produce lines, that is, vest lines. As the name implies, just like its name, it looks very much like a vest.

This development line formation process can help to strengthen the support of the waist and back, and also has very good stability to the spine. However, this phenomenon can not be practiced for a while, and it needs long-term persistence. It is difficult to do this without strong willpower.

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 standards of measurements are generally 84cm chest circumference, 6 1cm waist circumference and 90cm hip circumference. .
