Unless there is an express stipulation in the gym that you must wear fitness clothes, it is actually your choice and freedom not to wear them. It depends on the individual (including her own figure and habits) how much influence a girl does not wear underwear on sports. The influence on others depends on what others are doing in the gym.

Some people go to the gym just to rub the air conditioner, provide unlimited hot and cold water for bathing, pretend to punch in and see handsome guys and beautiful women. If it is the last purpose to go to the gym, it will be very influential if people don't wear underwear.

If you are a little fat, tights will do you more good.

Because the most terrible thing in sports may not be the impact force, but the * * * vibration caused by physical impact, the fatter friends are particularly vulnerable to the * * * vibration. The * * * vibration frequency of fat is very close to that of articular cartilage. The greater the volume and weight of fat, the stronger the effect of * * * vibration. At this time, tights can effectively help you reduce vibration.

Fingerless gloves: Cool gloves are worth matching. Not only because it's cool, but more importantly, gloves can play an anti-slip role when your palms are sweating, protecting you from being hurt by your hands under the fast pace of rotation. At the same time, gloves avoid direct contact between the palm and the handlebar, and will not make your delicate hands rough due to friction.

A thick towel: Putting a towel on the bicycle seat not only absorbs sweat, but also makes the cushion more comfortable.

In fact, in the end, I still want to say that whether you wear it or not is personal freedom. Anyway, there is nothing wrong with it.
