Hey NS. Your doing a great job drawing that arm down along the shoulder line.πͺ Notice how the hips are rotating first and the arm is still back behind you. That is how to generate power π₯ Now lets work on trying to get open more to the right sideline so that arm will be back behind you more. Then fire the hips so the belly button is pointed at the left antenna when you land and the torso is pointed to the left sideline.
Keep it up!π
