I'm just recently trying this new method since the falsetto method doesn't seem to work for me. I really hate my Adam's Apple anyway so that had me trying this method out.
What i would do every day is swallow, then my Adam's Apple would bob up. I would then hold it there for as long as I can until i can't breathe. I would not use my fingers to hold it there but i would to feel what's going on. When i do breathe with my Adam's Apple up i would feel it move slightly up and down and can't hold it there for much longer. The whole point of this was for my throat muscles to get strong enough to the point where my Adam's Apple can stay up there on it's own. I've been at this for the past couple of weeks but still nothing. I'm just wondering if i'm doing everything right since i'm getting frustrated and i don't wanna keep at this if i'm not doing it right and just wasting my energy.
When i speak with my Adam's Apple in that position my voice is in a female range but it doesn't quite sound perfect but that is fine because that is supposedly the next step.
It's not exactly how I do it or learned how to do it. It's the same muscles you use when you swallow but I only tighten the muscles just above the larynx. It causes the larynx to move up some and that puts you in the head voice. It doesn't require extreme force and after you have done it a bit, you automatic tighten up that muscle group before you speak. If I want to return to the old voice, I have to try hard to relax the muscles.
One thing you can try is starting at your regular voice and gradually increase the pitch. At some point your voice will break to a higher pitch and that's the cross over point between the chest and head voice. Kind of a reverse puberty.
