Hula hoop is a fitness tool, also known as fitness hoop. It became popular in Europe, America, Australia, Japan and other countries in 1950s, and then it was gradually introduced into China. Hula hoop has become a sport suitable for all ages because of its advantages of portability, beauty, portability, small floor space and moderate price.
Skillful use of hula hoop can effectively exercise waist and abdomen muscles, hip muscles and leg muscles, and improve the flexibility and flexibility of waist, hip and knee joints. Hula hoop can be used not only as a general toy, but also in competitions, acrobatic performances, or as a weight loss tool.
Hula hoop lovers should choose a circle with moderate weight, because it may have an impact on internal organs (such as kidneys) in the abdomen and back during swinging. A hula hoop that is too heavy has a strong impact and may hurt internal organs. Therefore, patients with lumbar muscle strain, spinal injury, osteoporosis and the elderly are not suitable for this exercise.

The latest development of the case
Brand information
In 1958, the popularity of hula hoop, an American plastic ring, was unprecedented. It is said that the place where no one plays with this kind of toy in the world is considered to be not fully integrated with the world, which shows that hula hoop has really become a global popular toy. Its origin can be traced back to Richard Nell and Arthur Merlin, two young toy manufacturers in San Gabriel, California. They jointly run a manufacturing company called Huim Ao.
The story took place in March, 1958, at a toy fair in new york, an acquaintance told them that there was a big wooden circle that was very popular in Australia, and children put it on their hips and played around. After returning to the company, Nell and Merlin began to try to make wooden circles, but they stopped after only about 20. They were not satisfied with wooden materials and decided to try using plastic. By May, they successfully produced products that met the requirements. They use colorful polyethylene pipes to make circles with a diameter of three feet, each with a price of 93 cents and a gross profit margin of 16%. Therefore, Huim Ao Company named this new toy Hula Hoop.
