partial hanging wire frame

[a lonely slob]

so i tried partial using the wire frame and everytime i start to feel something get tingly feel pressure etc. however the thing I'm doing it from might not be strong enough. its a wire frame coat hanger but is remarkably strong. I sat on top of it for about 3-4minutes (not a lot of ar so I had to get down) and it diidnt even bend. its fastened into the wall really tight also. should i sit on it again for longer to see if it works for sure or do you think it's ok? attaching some pics plus the belt i would use. any advice appreciated ty
