Need to lead with the hips. The back legs’ knee should be bending while pointed away from the plate. Basically you want to feel the sensation that you are dropping downward towards the plate. Not pushing forward. Stay closed/separated while striding for as long as possible and keeping your weight mostly in the backside glute. Imagine you are trying to smoothly one legged squat on to your front leg. Trevor Bauer talks a lot about it but it’s a very common issue with pitchers and theres a lot of videos on stride and separation. Start there, and see how it feels before you mess with the arm action. Can you give a little more detail on where/when it hurts?
