This is one of the biggest reasons I've stuck with pole dancing as long as I have. The physical benefits are great, but the feeling you get from mastering a move or expressing a particular emotion is indescribable. Just the other day, I assisted a student in her first climb. It was a huge deal for her and the expression of joy on her face reminded me why I do what I do.
The standard dance pole typically consists of a hollow chrome, steel, or brass pole with a circular cross section, running from floor to ceiling. Affixing at the ceiling gives more stability, but is not always realized, especially at night clubs with higher ceilings or at transportable devices. In most countries, including the United States, the diameter is usually 50 mm (2 inches), or the now more popular 45 mm (1.75 inches), allowing it to be gripped comfortably with one hand. In Asia, the diameter is usually 45 mm or less. In Australia a 38 mm pole is popular.
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.
