Conducive to perspiration and cooling. Pressure pants have the function of absorbing sweat, but we really don't need to put another layer on the outside during high-intensity exercise, which is very redundant. Maybe the sweat absorption and quick drying function of shorts is not so strong, and shorts are not good when they are wet.
Conducive to the display of specific actions. When we train biceps brachii, back muscles or abdominal muscles in the gym, we need to do some specific movements with great amplitude, and some movements need the help of coaches or others. In this process, the legs and crotch may be greatly stretched or squeezed. If we wear shorts, it will be inconvenient and even painful.
Conducive to safety. There are a lot of equipment in the gym that are "rod-shaped" or have other security risks. When we exercise, we maintain a high degree of concentration. Sometimes wearing shorts will catch some obstacles. If we fall or get hurt, it's not worth the loss, so try to wear close-fitting clothes.
It is conducive to spreading personal charm and enhancing self-confidence. Some girls may not be very confident psychologically in an open environment, even though she has a good figure. Then, when you can boldly show off your proud figure and get countless eyes in the relatively narrow closed space of the gym, it will undoubtedly greatly enhance your self-confidence.
Therefore, there is really no need to wear a pair of shorts outside the tights, which is tantamount to swimming in jeans. To do professional things, you must wear professional equipment.
Therefore, women who exercise in the gym are advised not to wear shorts outside tights.
But ... .
The scene where you need to wear shorts outside tight pants
What I just said was in the gym. If you are in an open environment, you still need to pay attention. After all, people of all ages are outside, and the environment is different. Just like swimming, no one will go to Square Street in a bathing suit, so try not to exercise outside in tights and shorts.
If you run in the park, if you run in the playground, if you run in the marathon, please wear shorts. It's a bit abrupt not to wear shorts in this environment.
So my opinion is: how to dress depends on the environment.
