My DD is getting in to a bad habit of tilting her head down to her non throwing shoulder when she throws overhand. Her throwing arm is almost stopping stiff straight out in front of her body also. She is not following thru with it across her body. The head tilting is also carried over to her pitching. Does anyone know what would cause this or ran into this problem before. How do I correct this problem. She seems to be putting way to much effort into her throws.
