What I think I am seeing is lack of gaining ground over the sagittal plane. ?? If that is the case a good drill to remedy?
bingo! She’s into her back hip instead of into the ground and back heel, which can cause reaching and or early barrel ‘turn’. Both are over compensations due to the lack of balance.
tell her to load into the ground while imitating Trout.
A cue I use is ‘let the gather pick up your front foot’. This will get the mass going forward and on top while the front knee gets under the front hip.. the ‘reach’ and early ‘turn’ will disappear.
