walkover

hello im in level 4 moving up to level 5 and i cant do a backwards walkover... on floor!! i know you must be wondering how i avoided it but i dont know! i can do them ok with a coach and we work lots on my shoulder and back flexibility but i cant do it, i cant even try and go back wards and...

My dd can get her front walkover 3 times out of 10. Does anyone have any tips or drills for this? Thanks.
