A kind of supine abdomen tightening apparatus for physical exercise

Abstract

The invention discloses a supine abdomen-tightening apparatus for physical exercise, which comprises a lying bed, a semicircular arc-shaped column movably arranged on the lying bed, a transmission unit installed on the lying bed, and a lying bed installed on the lying bed. For the leg pressing unit on the bed, an annular groove is opened on the arc-shaped column, and two through grooves for the arc-shaped column to pass are opened on the lying bed, and a groove for the sliding of the annular groove is arranged in one of the through grooves. The first fixed shaft, the lying bed is also provided with a second fixed shaft for the sliding of the annular groove. The equipment simulates the bending state of the human body lying on the back through the arc-shaped column, and uses the leg pressing unit to keep the training legs stable, thereby ensuring the training effect. In the process of pressing the legs, the training intensity can be changed at the same time, which greatly improves the training effect and efficiency.

Description

technical field [0001] The invention relates to a supine abdominal tightening device for physical exercise. Background technique [0002] Supine abdomen is a necessary exercise item in physical education. Supine abdomen exercise will use supine abdomen equipment. At present, the existing supine abdomen equipment is fixed and cannot be adjusted. It only provides a platform for lying down. The form and function are single, and it can only be exercised in a single way, and it is impossible to make corresponding changes for different training requirements. The trainer can only increase the training intensity by increasing the number of training, the training efficiency is affected, and the training is not comprehensive enough. poor effect. Contents of the invention [0003] In view of the above-mentioned technical deficiencies, the object of the present invention is to provide a supine abdomen retraction apparatus for physical exercise, which can change the training intensity...
