"Hula" is a traditional Hawaiian dance where dancers gyrate their hips, while hoop has means a ring. The hula-hoop is a tubular plastic toy, which is used by gyrating the hips.

The hula-hoop is one of the most popular products of the 20th century.

The 1950s were a period of intense development in the toy industry and even today many of the products developed during this time are still in use. Of particular note is the hula-hoop; no other toy has received the kind of attention heaped upon the hula-hoop, which is still in widespread use today. Hula-hoops were developed in the United States in 1958, and are still in use worldwide to this day.

Compared with other sporting goods, there is no risk of injury when using hula-hoops.

The function and design of hula-hoops has changed little since their initial development, until now. In particular the ring-shaped structure of the hula-hoop has never been modified.

However, a new unique hula-hoop has been developed, the Funkey-hula, which can be easily separated and assembled by users. In addition the weight of the Funkey-Hula can be easily adjusted to suit the user. By replacing curved portions of the Funkey-Hula with special protrusion handles, the Funkey-Hula can serve as a massage device.

How does it work? What is it?

Funkey-Hula is designed such that a plurality of wheels and protrusion wheels are located at one side of the hoop and a weight body is positioned opposite thereto, thereby generating centrifugal force by the weight body, which is operation principle of Funkey hula.

The conventional hula-hoops have drawbacks in that users, children and adults, should use the hula-hoops as purchased without consideration of their bodies, even though the hula-hoops are not complied with users' bodies. On the other hand, the weight of the Funkey-Hula can be adjusted to suit the user, such that it can be used by men, women, children, and the elderly alike.

Funkey hula is configured such that pluralities of wheels are located at one side of the hoop and a weight body is positioned opposite the wheels on the hoop. Accordingly, when the Funkey hoop is rotated with respect to the user's body, the weight body generates centrifugal force and the roll about the user's body, for example, about the waist.

Since the weight body of Funkey-hula is rotated at the far distance from the user's body, generating centrifugal force, the wheels opposite to the weight body are closely rolled around the user's body as the user swings his/her waist. Namely, the user's body, for example, waist, side, and belly, is repeatedly pressed as the wheels roll about the user's body. Such rotation of the wheels over the user’s body provides slimming effects as well as effects similar to therapeutic massage.

Operation principle of Funkey-hula is quite different from that of a conventional hula-hoop. Funkey-hula adopting the principle are variously designed such that their styles are new, beautiful, and polishing, which increasing their product values. The various styles of the Funkey-Hula provide a unique and aesthetically pleasing appearance, inviting users to exercise using the Funkey-Hula.

Funkey-hula adds in slimming the waistline as well as other portions of the lower body, without the risk of injury. The Funkey-hula massages the underbelly, waist, and sides as it stimulates spots on the body suitable for acupuncture, facilitates blood circulation, reduces fat, strengthens function of the bowels and prevents waist ache.

Handles additionally enclosed in Funkey-hula are designed such that protrusions and curves are formed on the surfaces thereof. Therefore, gripping the Funkey-Hula provides a massaging effect.
