What are the characteristics of sports bras? How to wear it correctly?

Sports bras are underwear that needs to be worn on specific occasions, and the characteristics can be explained from two aspects:       
1. Function: shock absorption. Provide good support and wrapping, avoid large shaking and swinging of the chest during exercise, protect the chest, and if you do not wear sports underwear for a long time during exercise, it is easy to cause damage or sagging to the chest. Sports bras are also designed with flexibility in mind, allowing underwear to fully stretch the limbs as much as possible.       2. Comfort: breathable and moisture-absorbent. It is easy to sweat during exercise, so breathability and sweat absorption are required for sports bras. In the fabric, sports bras generally have few pure cotton fabrics, more fabrics with mesh or quick-drying functions, but also consider elasticity, high-elastic fabrics are more conducive to sports, and the stitching process will be as flat as possible to increase the comfort of wearing.       
How to properly wear a sports bra that suits you? Three steps to get started:       
1. Reselect the size. The size of the sports bra is different from the size of conventional underwear, generally marked by S/M/L (large, medium, small), etc., it is best to re-measure your upper and lower bust data before purchasing, in most cases the following bust data as a reference for size selection, you can consult with the merchant for details.       
2. Confirm exercise intensity. The intensity of different sports is not the same, and the degree of vibration in the chest is not the same, which requires us to choose the corresponding sports bra according to the intensity of the exercise we are involved in, and some common exercise intensity is divided as follows: High-intensity exercise: aerobic dance or aerobics, running, badminton, volleyball, basketball, football, etc.;       Moderate intensity exercise: cycling, brisk walking, race walking, climbing, mountain climbing, aerobic pedaling, etc.;       Low-intensity exercise: yoga, Pilates, walking, golf, body dance, etc.       
3. Try on the upper body. Sports bras are best tried on on the upper body, everyone's body shape and chest shape are different, and the feeling of wearing it is also inconsistent. Put the sports bra on the body, feel whether it fits the body, and then do some running and jumping movements to see how wrapped the underwear is, whether the support force is enough to absorb shock, and there will be no obvious shaking and pain in the chest.       There is a small test of whether sports bra fits the fit: you can insert 2 fingers under the shoulder strap to see if it can slowly slide between the shoulder strap and the skin, if it is too tight or too loose, it is not very suitable.
