Why is it so difficult for me obtain girth? I am thankful to have gained about 1” in length, but I don’t seem to improve in girth. I do horses and bends and uli #3. I get a temporary gain of about .25 inches, but the next day it seems to go back to original size. Is the temporary gain from edema or something? Also, does anyone actually know what the tunica is made of? Is it similar to facia?
