A kind of aerobics flexibility training auxiliary device

Abstract

The invention belongs to an auxiliary device for aerobics flexibility training, which includes supporting legs and side legs. There is a connecting rod between the supporting legs. There is a boss in the middle of the connecting rod. There is a central shaft on the boss. A spring, with a central rod structure on the upper side of the central shaft; an L-shaped rod on the side of the middle part of the supporting leg, and a support rod on the L-shaped rod, and a first lock tube structure on the lower side of the L-shaped rod. There is a pry bar in the sleeve, and there is a second lock tube structure on the outer support rod of the pry bar; there are lug plates at the upper end of the support legs, a rotating rod is hinged between the ear plates, and a locking structure is located outside the ear plates; the upper end of the rotating rod is hinged with a side There are several third through holes at the hinge on the outer side of the side bar, and there are locking blocks on the outer side of the side bar; the present invention can be performed on different heights and waist heights, greatly improving the safety and applicability of the present invention, It can quickly improve the flexibility of the trainer, and avoid the trainer's waist falling directly to the ground due to exhaustion and causing injury.

Description

technical field [0001] The invention belongs to the technical field of aerobics training devices, in particular to an aerobics flexibility training auxiliary device. Background technique [0002] Flexibility is an important part of physical fitness. It refers to the range of motion of each joint of the body and the elastic stretching ability of ligaments, tendons, muscles, and other tissues that cross the joints. .After the flexibility is fully developed, the range of motion of the human joints will be significantly increased, and the flexibility of the joints will also be enhanced. In this way, the movements are more coordinated, accurate and graceful, and at the same time, it can reduce the damage of joints, muscles and other soft tissues caused by increased movement range and excessive torsion in sports activities and daily life. [0003] There are many ways to train flexibility, such as vertical fork: trainees straighten their legs, press down separately from front to b...

Problems solved by technology

When practicing this action, you need to use external objects for auxiliary exercises. When using external objects such as walls, although you can slowly lower your waist, it is inconvenient to get up after the lower waist is completed. When the trainer's shoulder strength is exhausted, it is difficult to It is also difficult to effectively support the body when getting up smoothly, and it is easy to cause damage to the back and spine after falling directly, which brings great unsafe factors to the trainer

While training with a partner, first, it wastes the training time of the partner, and the efficiency is poor. Second, the artificial cooperation cannot lift the trainer in time, and it is very likely that the trainer will be pressed
