Foundation of Movement
So often, with overhead athletes, we neglect the foundation of where movement starts. Here, Sadie is performing a front box squat (right), as well as a good hip mobility exercise (left).
It is important for throwing athletes to maintain proper thoracic spine (upper back) mobility, as well as hip health and mobility. Rotation should be initiated from the T-spine, not the lower back, and power movements are most effective when coupled with mobility and stability of the joint in question.
