Abstract

The invention relates to the technical field of aerobics equipment, in particular to an adjustable aerobics teaching aid which comprises a hand rest, a split limiting mechanism and a base, and the hand rest is fixed at the front end of the top surface of the base; the split limiting mechanism comprises a distance adjusting rotating wheel, an internal thread rotating pipe, a fixing screw, a liftingplate, a push-pull support, a linkage frame and a limiting baffle plate. The distance adjusting rotating wheel is fixed at the top end of the internal thread rotating pipe; the upper end of the fixing screw rod is matched with the interior of the internal thread rotating pipe through threads; the lower end of the fixed screw rod is fixedly connected to the base; the internal thread rotating pipeis rotationally connected to the middle of the lifting plate through a mounted bearing; the split limiting mechanism is arranged in the split training device, the outer sides of the two feet of a trainee can be supported, when the trainee conducts split training, the angle can be gradually increased, the trainee adapts to the split movement process, the training purpose is achieved, and meanwhilethe health of the trainee cannot be affected.

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. ...
