Description

Technical Field

[0001] The invention relates to the technical field of outdoor development equipment, and in particular to an extreme challenge hourglass tower. Background Art

[0002] As people's living standards continue to improve, people's pace of life is getting faster and faster, life and work pressures are getting greater and greater, and people are paying more and more attention to physical exercise. People are not only satisfied with various indoor fitness exercises, but are more willing to participate in outdoor sports. Outdoor sports can not only strengthen the body, but also get close to nature, relax the mind, hone people's will, and have a more positive attitude towards life. Therefore, various outdoor expansion training equipment has also emerged.

[0003] At the same time, outdoor development is also called experiential training. For corporate teams, it can effectively stimulate the potential of corporate personnel and strengthen the team's spirit of cooperation. Outdoor development sports have a history of fifty or sixty years in foreign countries, but it was not until the 1980s that outdoor development sports began to be introduced into my country from Europe and the United States. In recent years, outdoor development sports have been booming among young people in some developed regions and large and medium-sized cities in my country. Outdoor development sports have the characteristics of comprehensive activity, adventure, and challenge.
