My DD is working on learning the L4 floor routine and one of the biggest challenges is the arm movements. She got the routine down and the lower body looking great but her arms are a mess. They are bent when the are supposed to be straight and she has trouble remembering to raise and lower the arms at certain points. I think she is having trouble concentrating on both upper body and lower body together. Any sugguestions besides more practice to help her focus on arms? Also the arms movements at the beginning of the routine on so stiff it looks terrible. How can I help her fix the stiff arms at the beginning to look better?
