  The present invention relates to an exercise wheel, and more particularly, to a novel crank type double exercise wheel.

  Currently, the exercise wheel is a sport exercise goods that is widely spread and often seen. Exercise wheels are preferred by muscle training enthusiasts and gym users because they have the advantage of being simple in construction, not occupying space and having good training effects.

  As known to those who use exercise wheels, a conventional exercise wheel is composed of one wheel and two holding bars projecting from the center of both sides of the wheel. After the user holds the two holding bars with both hands and then pushes or pulls the wheel, the forward / backward movement of the wheel is controlled, and the muscle skin such as arms, waist / back, and feet is thereby controlled. You can do the training. However, when using such a traditional exercise wheel, it is not possible to change the altitude of both hands holding the two holding bars, so the use of the exercise wheel is monotonous and the muscle training effect is further improved. There are problems and drawbacks.

  In order to solve the problems and drawbacks of the exercise wheel described above, the related industry has developed a new exercise wheel. In the conventional exercise wheel, the two holding bars protrude coaxially to the center on both sides of the wheel, but in the new exercise wheel, the two holding bars are not coaxial in the center on both sides of the wheel so that the positions of the two holding bars are different. Protruding. When using the new exercise wheel, the user can control the forward and backward movement of the wheel by holding or holding or pushing the two holding bars with both hands. In this case, the two holding bars projecting non-coaxially at the center on both sides of the wheel cause a difference in the front-rear direction and a difference in the altitude direction in both hands of the user, realizing a variety of movements. The muscle training effect can be further improved. However, when using the exercise wheel, the two holding bars cause a difference in the front and rear direction and a difference in the altitude direction in the user's hands, so the force received by the user's hands is different, and the user is balanced. There is a risk of breaking. In addition, since one wheel formed between the two holding bars cannot provide a stable support force to the body, the user must keep balance by the strength of the arm and the body. It is difficult and too dangerous to balance with muscle strength in several parts of the body. That is, since there are safety problems that cause ligament damage, sprains, etc., a solution to solve the above-mentioned problems must be considered.
