Description

Technical Field

[0001] This utility model relates to the field of sports exercise equipment, specifically a multifunctional waist twisting machine. Background Technology

[0002] A waist twisting machine is a common home or gym fitness equipment, mainly used to exercise the waist, abdomen, buttocks, and core muscles, helping to shape the body, enhance flexibility, and promote blood circulation. Patent CN202219063U discloses a kneeling waist twisting machine, including a base, a support pole, left and right handles, and a damping device. The base has left and right kneeling pads, and a rotating component is pivotally connected to the front of the kneeling pads. The support is located at the front of the base, with its bottom end connected to the rotating component and its top end connected to the left and right handles, which are linked to the support and the rotating component. The damping device consists of an adjustment knob, upper and lower friction plates, and upper and lower pressure plates. The upper friction plate, in conjunction with the upper pressure plate, is located on the top surface of the rotating component, and the lower friction plate, in conjunction with the lower pressure plate, is located on the bottom surface of the rotating component. The adjustment knob, combined with a spring, presses the upper and lower pressure plates together. The user kneels on the left and right kneeling pads of the machine base, holds the handles with both hands to overcome the resistance of the damping device and exert force to the left and right. This will cause the rotating parts to rotate relative to the machine base through the linkage of the upright rod. This process causes the user's body to twist back and forth, thereby achieving the purpose of twisting, relaxing and exercising the waist.

[0003] The aforementioned patents have relatively limited functionality, allowing users to perform waist-twisting exercises while kneeling on the left and right kneeling mats, without providing additional movement modes for the user's legs. Utility Model Content
