An adjustable aerobics teaching aid

Abstract

The present invention relates to the technical field of aerobics equipment, and more specifically relates to an adjustable aerobics teaching aid, comprising a hand support, a splitting limit mechanism and a base, the hand support is fixed on the front end of the top surface of the base; The splitting limit mechanism includes a distance adjusting wheel, an internal threaded rotating tube, a fixed screw, a lifting plate, a push-pull bracket, a linkage frame and a limit baffle; the distance adjusting wheel is fixed on the top of the internally threaded rotating tube; The upper end of the fixed screw is threaded into the internally threaded rotary tube; the lower end of the fixed screw is fixedly connected to the base; the internally threaded rotary tube is rotatably connected to the middle of the lifting plate through a bearing with a seat; the interior of the present invention is provided with a split The limit mechanism can support the outside of the trainer's feet, so that when the trainer performs the splits training, the angle can be gradually increased to adapt to the process of the splits movement, so as to achieve the training purpose without affecting his own health.

Description

technical field [0001] The invention relates to the technical field of aerobics equipment, and more specifically relates to an adjustable aerobics teaching aid. Background technique [0002] Aerobics is a physical education course offered by many colleges and universities. It is mainly to practice the flexibility and flexibility of young people, and at the same time to practice the strength and shape of young people. Aerobics has very high requirements on people's flexibility. In flexibility training, leg presses or splits are often used for training. However, in the process of splits and leg presses, it is difficult for the trainer to maintain the opening and closing angle of the legs. When the trainer does the splits, the weight of the body will be distributed to the legs. Improper training can easily cause muscle strain. For beginners Generally speaking, the splits cannot be successful at one time, and it is necessary to gradually increase the split angle for training. ...

However, in the process of splits and leg presses, it is difficult for the trainer to maintain the opening and closing angle of the legs. When the trainer does the splits, the weight of the body will be distributed to the legs. Improper training can easily cause muscle strain. For beginners Generally speaking, the splits cannot be successful at one time, and it is necessary to gradually increase the angle of the splits for training. The existing training devices cannot make it difficult for the trainer to maintain the opening and closing angle of the legs, and it is easy to cause the opening and closing angle to be too large and strain the muscles.
