I have a question in regards to my 6 year old daughter who is currently doing gymnastics.
She has made some INSANE improvements this year year. However, 1 things she has issues with is a bridge and subsequently a bridge walk
Her form looks alot like: 
When I watch the other kids their wrists are under (or really close to under) their shoulders. My daughter has her arms more like the position I posted in the picture and I can only assume that makes a bridge WAY harder.
I am trying to figure out what the issue is:
- Lack of thoracic mobility?
- Lack of Shoulder mobility?
- Other?
The coach suggests kids practice stuff at home (currently she trains for 2 hours once per week) when they are watching TV, etc.
Any ideas?
