Huh, interesting idea overdose. So probably not useful for a hanger you think?
I think there is an interesting caveat here: maybe the hand ISN’T the ideal instrument for hanging. Good for short, intense stretches, yes. But maybe not the best for applying force for 20 minutes at a time due to circulation and glans issues. After all, Tom Hubbard originally based the AFB on the hand’s position while stretching, and it doesn’t feel nearly as comfortable as other modern compression hangers like the Bib.
I think maybe the only legit and comfortable way we have discovered to hang from the glans is the vacuum hanger, but these have their limitations as well.
