I found
penis qigong videos on youtube. Hanging weight they brag about there is 100kg-240kg, as far as deadlifting. I was curious because I can work out with one minute sets with 155 pounds and it seemed like that might be getting interesting. Not so much.
One video shows that they use a silk cloth tied to their penis with a girth hitch. Another video shows a penis qigong student resting his body weight on a jagged broken bottle. I think that tying a girth hitch on a penis to hang hundreds of pounds is roughly the equivalent of leaning on a jagged edged broken bottle until the bottle explodes and the man is unhurt. If you want to hang using a girth hitch knot, start with one pound and go up in half a pound increments after five days, until you give up on girth hitch as a hanger like a good western euro unbeliever. I haven't tried a girth hitch. I guess I have to. I may reach 100kg deadlift if I can work out in one minute sets with 155 lb now.
