Having a beautiful calf curve is an important symbol of female bodybuilding, but do you know what kind of calf is the standard? Like the picture, beautiful legs also have their proportions and sizes, and their calculation methods are as follows: calf length: greater than 26.3% of height; Maximum girth: about three-quarters of the length of the calf; Measurement: Last week's length is equal to the maximum circumference, the middle circumference is last week's length plus next week's length divided by 2, and next week's length is 63% of last week's length. Based on this, if your height is 160 cm, then the standard length of your calf should be 42 cm, the maximum girth should be about 32 cm, the upper girth is 32 cm, the middle girth is 26.5 cm and the lower girth is 20 cm. Viewed from the side, the leading edge of the ideal calf curve should be vertical and the trailing edge slightly arched; From the front, no matter the front or the back, the inner edge should be a vertical line, while the outer edge should reflect a certain radian. The proportion of the calf curve also needs to take into account the body line. (Kathy Women's Network) Understand the leg standards of oriental women and pay attention to diet and exercise.

When you fall, the forefoot touches the ground first, and then the whole foot touches the ground. Take off on tiptoe again, 10 times in a row. 3. Massage the calf. Sitting posture, relax calf muscles, gently massage calf muscles with both hands, and massage each leg for 2 ~ 3 minutes, each time.
