Parallel bars made of wood and steel bars for outdoor playground

Parallel bars practice is a typical movement practice for students to develop support and support swing under the condition of bearing their own weight. It plays an important role in making up for the imbalance of upper limb and trunk strength development. By doing the exercise on parallel bars, it can effectively develop the strength of players' upper limb, shoulder belt and trunk muscles, especially the development of deltoid muscle, pectorals major muscle, abdominal muscle and dorsal muscle, and enhance the flexibility and flexibility of elbow, shoulder, lumbar joint and ligament.

Through various forms of swing, leg separation, rotation, push and other movement exercises, improve the body's self-regulation and control ability in time and space, and play a positive role in students' balance ability, support and coordinated development.
