Robby I treid what you sugested, I hope I understand it. I placed my hands on ground, open my palm wide, press hard on the floor with whole hand and fingers, tensioned forearms and started leaning forward. Suprisingly I could go to the point my shoulders couldnt hold me. It felt like my whole lower arm getting stretched, but I didnt feel any strong or sharp pain and it also feel kinda safe and nice. Im definitely gonna continue with this drill, try to play with it and let you know what happen, but for now its seems like it working pretty well, thanks.
