Relieve pain, prevent injury, and increase performance. Get customized mobility coaching developed by Dr. Kelly Starrett.
Hands need to be moved out. Shoulder width or wider
Your husbands hand positioning is better.
Can you re create the overhead archtype?
Are you in an organized active shoulder position?
Has anyone looked at your technique/movement patterns with the jerk and push press?
When your hand positioning is too close or there are restrictions somewhere within the system your body makes adjustments you may or may not be aware of so you can complete the task/movement.
Your husband is seeing improvements, but there is more to go to work on especially if there are deviations in bar path or technique.
These movements should not be painful.
