1, depending on the intensity and type of exercise. For example, for relatively low-intensity sports, you can generally choose a simple fixed bra. Simple fixed bra is a kind of elastic net bra, which belongs to pressure fixation, and its structure is generally simple, because the requirements for fixation are not high. It is advisable to choose products with high cotton content to avoid oppression on the chest.

Moderate-intensity sports bras mainly rely on elastic fabrics to form a certain pressure on the breasts to achieve a fixed effect. Compared with low-intensity sports bra, it is more strict in tailoring, which requires full consideration of the shape and structure of breast and the stress on shoulder and back.

In the process of high-intensity exercise, shaking the chest is the most intense, and if it is not protected, it will do the greatest harm to the chest. High-intensity exercise requires the highest support and fixity of sports bra, which should have good fixity and no obvious discomfort and pressure on the chest.

2, the size of the cup, the bigger the cup, the greater the support. The girls in AB Cup are relatively happy, and most sports bras can provide you with adequate protection in various types of sports. For C+ girls, there is a need for products with better support and protection. For example, in low-intensity exercise, it is good for girls with A/B cups to wear medium support, and those with C/D cups and above need to wear high support.

3, clothes can not be too tight, can not produce a sense of depression. Tightness is not equal to strong support. A sports bra that can provide strong support must be a "constant pressure type". Through the elasticity and style design of the fabric, pressure is generated, and the breasts are securely and firmly fixed without excessive displacement during exercise. The stress caused by tension is not good for thymus, which may lead to breast diseases such as hyperplasia of mammary glands.
