I am still surprised that people don't understand this concept. In order for skin to grip the pole, pole dancers must have their legs, arms and stomach exposed. This is a safety concern. There are some grounded spins, poses, and floor work that can be performed while wearing pants. But in order to perform more advanced moves, we must have the proper amount of skin exposure. Most pole dancers do not have an issue with this at all, since our focus turns away from what our bodies look like and onto what they can do.
The use of pole for sports and exercise has been traced back at least eight hundred years to the traditional Indian sport of mallakhamb, which utilizes principles of endurance and strength using a wooden pole, wider in diameter than a modern standard pole. The Chinese pole, originating in India, uses two poles on which men would perform "gravity defying tricks" as they leap from pole to pole, at approximately twenty feet in the air, further information can be seen in the old vintage documentary series of mallakhamb, by yasho purush film on YouTube.
