Trying to Shallow

Hi Tim, I'm just another member but hoping to help a bit. As you change your pattern especially getting your hands to work differently and release differently, especially going from steep to shallow arms, I would expect for everything to feel powerless and weak. I believe this is why Tyler recommended starting with much smaller motions like delivery and go. Separately it might be helpful to take a look at just the orientation of his body and compare with yourself in this video https://www.golfsmartacademy.com/golf-instruction/lead-arm-shallow/?q=steep%20body%20shallow%20club. Worth noting that there are body/pivot shallowing/steepening moves that match up with arm steepening/shallowing moves to equal out to your swing plane. Note that from FO his shoulders are still level this point where as your trail shoulder is very low. Also note how hit club shaft is a big more left, almost at his forearm where yours in more across your shoulder.
