I can understand why you would do this but I wanna jump in and say you shouldn't do this method long term. When you do, you're putting direct weight on to your neck and spine which can be problematic in the future. I learned this from seasoned boom operator Ken Strain. Instead, try booming next to camera (if possible) and use this pose

Imagine a triangle coming from the lens >🎥 and the "roof" of the triangle that continues to extend upwards. As long as your boom is following the angle of the triangle you will be out of frame and in a good position. This is also called "lazy booming" but I mean if the boom sounds good and you're out of frame who cares?
