Hi newme.
There are some very knowledgeable members that believe LOT doesn’t really apply. At any rate, as was pointed out, LOT is a theory. Two inches in one year doesn’t happen, or if it does it’s rare. Don’t rush into hanging. You should simply follow the newbie routine to start with (read and understand well it before beginning). If you do get into hanging later on, you need to make sure you’ve read, read, read about it first. Make especially sure you know all the precautions. It’s quite dangerous if not done properly. You only have one dick. In fact, all the various exercises are unsafe if not done properly.
Sounds to me you haven’t read enough here to begin with, or you would know that 2 inches in the first year is unrealistic, hanging too soon isn’t recommended, and that LOT theory isn’t believed by everyone. I’m pointing this out because I don’t want you to get injured because you rushed into exercises.
