Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to a rotary stepper. Background Art

[0002] Modern people pay more and more attention to physical maintenance, and the most advocated health care method is exercise. However, modern people are busy with work and live in crowded environments, so it is rather troublesome to find free time and a suitable place for exercise. Therefore, many fitness equipment have been introduced on the market for users to exercise at home, including steppers. A stepper is a common fitness equipment, which is easy to install, occupies a small area, is convenient for daily home use and storage, and can burn calories, increase heart rate and aerobic respiration ability. It uses the up and down swing of the left and right pedals to simulate stepping actions such as brisk walking and going up stairs, so as to train the leg muscles and achieve the effect of exercise. The structure design of the traditional stepper is not reasonable enough, and its function is relatively single, only able to achieve simple stepping motion, which is rather monotonous. The Chinese utility model with the application number 201620711043.5 discloses a rotary waist-twisting stepper, which fixes the pedal machine on the base through a rotary fixing seat and a rotary disk, and can not only achieve the function of stepping, but also achieve rotary waist-twisting. However, the device does not limit the rotation angle of the pedal machine, so that users need to hold the handrail when using it. If they accidentally let go, it is easy to rotate too much and cause danger, and its safety cannot be guaranteed. Summary of the Utility Model
