Stability must be established before movement. In dance, the shoulder girdle must be strong to support the movement of the performer’s arms. Arm movements help to counter the movements of the legs and neck. In dance, movement will not be controlled or graceful without strength and stability in the shoulder girdle, abdominals and pelvis.
Endurance in the scapulothoracic muscles ensures the following:
1. The dancer avoids developing tension in the upper traps
2. Graceful movement in the arms and shoulders
3. Balance, jumps and turns are effortless
Here is a lat pull down and core strengthening exercise on the Pilates Tower Trainer.
