On the premise that the driven arm 7 and the balance arm 16 move simultaneously, the transmission mechanism also realizes that the rotation directions of the driven arm 7 and the balance arm 16 are opposite, for example: when the driven arm 7 drives the vertical weight plate 14 to rotate towards the left lower side, the balance arm 16 drives the balance weight plate 17 to rotate towards the right lower side, so that the left and right gravity center deviation caused by the vertical weight plate 14 and the balance weight plate 17 is counteracted, the larger up and down gravity center deviation caused by the vertical weight plate 14 and the balance weight plate 17 being in the same up and down direction is only left, and the anti-interference balance physical training has a good effect.
