Kneeling during Walk

A beautfiul day spent in the arena trotting and kneeling and walking up and down hills. My 4 year old client has to work very hard to keep her knees together, tummy in and bottom up while in the kneeling position during a walk and also while stationary as she removed toys attached to a bottle with velcro and inserted them inside. This is a great positon to work on her core strength. She also tolerated prone extension position which she held to the count of ten before dismounting.
