Not suitable for children? The world's top five most popular nude sports

Nude culture is a topic worth hyping. From nude villages to nude gatherings in cities, modern civilized people have challenged the constraints of civilization countless times, taking off their clothes and promoting primitive physical and spiritual liberation.

But working out while naked is something many people have never imagined. Earlier this year, a fitness center in the Dutch town of Hetland launched a "Naked Sunday" event. On this day, all gym goers, regardless of gender, age or status, were completely naked, playing with the equipment while letting the sweat flow down their skin, which felt very magical. Coincidentally, a yoga experience center in San Francisco, USA, also offers nude yoga classes. There are 90-minute nude yoga classes on Sundays, with no restraints and full of meditation.

In Beijing, working out naked is unthinkable, but maybe you can try it at home.

Around the world, including in remote towns in China, it is common to exercise naked, such as skinny dipping.

These people who are used to exercising naked, from acting alone to acting in groups, have gradually formed a circle of belief in naked fitness. Here, not being naked is actually a strange thing.

Location: San Francisco, USA

Surprise Index: ★★★

A nude yoga experience center in San Francisco offers 90-minute nude yoga classes every Sunday. Practitioners gather together, take off their clothes, and meditate together. Then men and women went to their respective areas and finally gathered together. The experiencer wrote: "Naked yoga allows people to experience a kind of movement without restraint and hindrance; it also allows people to breathe freely, improve body balance and function, and make people feel detached from the world, open, liberated, and welcome."

Compared to exercising naked within a small niche, with men and women separated, it is not shocking. People pursue a circle of friends with similar interests and have a good balance between freedom of expression and privacy protection.

Event: Nude volleyball

Location: Southern California, USA

Surprise Index: ★★★★

Nude volleyball is very popular abroad. It is in the same vein as nudist sports and attracts a group of people from different professions to participate in this sport with the concept of returning to nature. The most famous of these is the "Nude Volleyball Club" in southern California, whose members even include people in their 70s. These people regularly arrange competitions, usually on beaches, valleys, etc. where there are fewer people. However, their volleyball games are gender neutral, which is still unacceptable to outsiders.

Event: Nude swimming

Location: Nice, France, Dise Beach in Greece, Wreck Beach in Vancouver...

Surprise Index: ★★

Nude swimming is closely related to nude villages. In these places, it is normal for people to sunbathe on the beach or swim in the sea without clothes. The bikini girls who cover themselves up and are a little shy become the laughing stock of everyone. You can enter the village, but you must also be naked and you cannot stare at others. In some places, taking photos is not allowed unless approved. Here, you can swim naked or do water aerobics, enjoying the freedom and relaxation of a fish by the sea. Nude swimming in the nude village has a history of more than 80 years and is no longer a strange thing.

Project: Nude skiing

Location: Klebenstein, Austria

Surprise Index: ★★★★★

Austria's ski resorts actually have nude skiing programs. They choose to go skiing naked collectively from mid-March to April when the weather is not too cold and the sunshine is sufficient. The heat generated from skiing is enough to keep out the cold. Participants may wear hats, gloves, sunglasses and shoes. This kind of fitness is truly unique.
