I am looking for advice on how to help my daughter deal with arm & elbow pain. During her bars rotation (she's a Level 4, 6-yrs old) they are working alot on the proper positioning on the bar ~ straight arms, thighs against the bars while maintaining the hollow body. She has great form, tight legs, pointed toes, and she keeps her body above the bar to where they mark her legs but she just cannot seem to straighten her arms. My guess is she needs to work on her triceps more? Any good exercises you can recommend. Unfortunately, I've contacted her coach but haven't heard back from her yet. Maybe I can get a quicker response here! TIA!
