[0002] Core strength training refers to the training of the strength, stability, balance and other abilities of the core area muscles (mainly the abdominal, lower back and pelvic muscle groups) and their deep small muscles. It is different from traditional waist and abdominal strength training, and is to develop and improve the whole prime mover and local stabilizer muscles in the core area through training. The purpose of core strength training is to coordinate the whole body to ensure that the core muscle group plays a role in stabilizing the body and transmitting energy when the trainee performs an action. One of the common core strength training methods is unstable training.

The center movable ball head moves in all directions in the center movable ball groove seat, the top pushing inner arm rod slides up and down in the top pushing outer arm pipe, and the two ends of the top pushing spring are respectively in contact with the bottom top pushing base and the supporting base. Through the top pushing of the top pushing spring, the universal top pushing wheel at the top of the top pushing inner arm rod is in contact with the bottom end surface of the balance training table. The balance training table moves in all directions above the supporting base with the center movable ball groove seat as the center. In this way, the martial arts free combat balance training table assembly forms a balance training standing table structure on the training supporting base assembly. The driving structure of the patent uses a movable ball to realize rotation. The surface of the movable ball is easy to wear during use. In addition, the above-mentioned patent uses a plurality of spring structures, and the structure is relatively complex and the supporting stability is not enough. SUMMARY
