My 10U daughter on her follow through where she stops her arm and draws it up like "T-REX". She has been in lessons for 1yr learning IR and fought getting long arm from the beginning and this is her natural movement on the mound (She throws low to mid 40s). She had forearm pain in the spring/summer but the DR thinks it was from overuse not necessarly this movement. Her instructor thnks this movement played a part as well. Are there any drills or instruction she could to break this habit?
