Tendu Exercise BallHaving a strong foot, is critical for any dancer, whether on pointe or not. Very heavy demands are placed on the foot during dance and any weak arches, rolling feet or weak ankles can affect the alignment of the whole body. This can lead to acute to chronic problems with the foot, ankle, knees, hips or back. If the foot muscles are strengthened, you can have greater stability, better alignment, and more flexibility.
