Are these boys or girls? Get the hair out of your face. They are both off balance at the foul line. Rushing is an issue too. Fall left, fall left. Slow down. Take your time. Head needs to be aligned with elbow and foot. Stop the rushing. Very off balance at foul line
1 They are boys and 2 we have been working with both of them on everything you mentioned. We're working on breaking 4-5 years of self taught "bad" form... it will take a bit but we are making slow progress.
