Abstract: An eccentric column structure of a waist twisting exercise machine is provided which includes a base, a cushion, and an eccentric column assembled between the base and the cushion. The cushion is supported above the base through the eccentric column, so that the seat height of the cushion is slightly higher than the height of knees of an average adult, thereby enabling riding in a relatively comfortable and ergonomic posture, and enabling exercising movements of rotating and waist twisting by using two feet landing on the ground as points of force application. In addition, the eccentric column is integrally formed by a bending processing of a metal pipe column, which not only avoids the formation of seams during assembly or structural weaknesses derived from welding, but also greatly enhances the overall strength of the structure, thereby being conducive to prolonging the service life and safety of the exercise machine.

Abstract: A stepper exercise machine is provided. When a pedal is pedaled by a user, a drive gear is rotated forward or rearward. One end of a link is rotated about a drive rod, and a turning lever connected to the other end of the link is confined by a second accommodation trough of the pedal, so that the link brings the pedal to move in the up-down direction and the front-rear direction. In cooperation with a shaft which is fixed, a sleeve is rotatable relative to the shaft. When the pedal is driven, a first accommodation space provides a space for the pedal to move in the front-rear direction. By means of the action of two flywheels to provide an acceleration effect, the rotation of the drive gear is to speed up, so that the user can reduce the force exerted to the pedal.
