Abstract: A ball chair may comprise a chair frame, a ball body and an adjusting unit. The chair frame has a connecting base and a legs base, and a supporting column formed therebetween is configured to achieve a telescopic action thereby adjusting a height of the ball chair. The connecting base is formed in a concave shape to form a housing space therein, and an annular frame is formed at an upper end of the connecting base. The ball body is configured to be coupled on the connecting base of the chair frame, and the annular frame is configured to couple with an outer periphery of the ball body thereby limiting a position thereof. As a result, the ball chair is suitable for different statures of users and enables the users to sit thereon for training or rehabilitation.

Abstract: A ball chair may include a chair base and a restricting unit. The chair base has a circular receiving space to receive a ball and an inner portion of the receiving space has a connecting portion that has at least two through holes. The restricting unit has an arc board and a connecting post conjugating with the connecting portion. A restricting board extends from the arc board corresponding to the connecting recessed portion, and the restricting board is protruding from an upper portion of the receiving space. The connecting portion of the chair base is provided for the restricting unit to restrict the ball, and the restricting unit and the connecting portion can be quickly and easily engaged increase the convenience during the assembling process and prevent the ball from being damaged.

Abstract: An electronically controlled damping structure in fitness equipment may include a base, an adjusting unit and a driving component. A passive component of the adjusting unit can move in a receiving space of the base by the driving component to adjust the distance between the passive component and a top unit to further adjust the resilient coefficient of a buffer unit. So, when the user is exercising on the fitness equipment, he/she does not have to adjust the damping manually to increase the practicability of the fitness equipment, and it is more convenient for the user to adjust the damping.

Abstract: A gyration type exercising device includes a gyration unit (10), a damper (20) and a drive handle (30). The gyration unit includes a mounting frame (11) and a rotation wheel (12) rotatably mounted on the mounting frame and driven by the drive handle. The rotation wheel is provided with a rotation shaft (121). The drive handle has a first end pivotally connected with the rotation wheel and a second end provided with a holding bar (31). Thus, when the user's two hands hold the holding bar to move the drive handle in a gyration manner, the user's body has to move forward and backward and has to exert a force on the drive handle successively to rotate the rotation wheel reciprocally so as to exercise the user's body completely.

Abstract: A full body twisting exercise machine has a support frame comprising a lower layer portion and an upper layer portion, a bearing respectively installed at the lower and the upper layer portions, a revolving shaft disposed though both bearings, one end of the revolving shaft protruding from the upper layer portion and connected to a crank and having an extension bar, a free end of the extension bar having a connecting portion; a connecting rod, a driving rod and a handle, an aperture of the connecting rod pivoted to the connecting portion of the extension bar and secured to one end of the driving rod; another end of the driving rod connected to a handle; and a flywheel disposed between the lower layer portion and the upper layer portion and jacketing the revolving shaft, and the lower layer portion of the support frame having a damping device.
