Description

The present invention relates to a chair training device.

BACKGROUND ART Conventionally, various types of training equipment have been proposed for training the body. Such training equipment is not limited to use in sports performed at a very high level in order to improve the motor function of the body like an athlete, but it is also used for high-intensity training such as dieting for women and walking training for the elderly. However, there is also a demand for training equipment that can be easily performed.

As such a training device, a training device using a tube made of rubber or the like has been proposed. A tube made of rubber or the like is lightweight, compact, and inexpensive, so it is used as a simple load means for training equipment (Patent Document 1). However, if a tube made of rubber or the like is used as an additional means to enable various types of training, there is a drawback that the device becomes very large. In addition, when one end of a tube made of rubber or the like is supported by the device and the other end is fixed to the body or gripped for use, the length of the tube must be secured to some extent. Since it is not possible to ensure the appropriate exercise intensity and movement distance, there is a problem that the exercise part must be exercised in a state that is separated from the support point to some extent.
