Problems solved by technology

However, in the current folk dance training, the flexibility training of the legs usually uses some simple equipment to perform leg pressing and leg splitting exercises, and generally all are fixed equipment, which still requires manual effort to press the legs, and the time required for each leg pressing The force used is not standard and uniform, which makes the whole body exercise very tiring, and it is still unable to achieve effective flexibility training for the legs. Therefore, it is difficult to achieve very effective and very effective exercises due to the inability to achieve standard and automatic exercises. Rhythmic Leg Flexibility Training
