Did some experiments on my height:
167cm after heavy squats
170cm after a short walk
175cm after hanging on a bar
176cm after hanging on a bar with weights
After hanging, I'm taller than normally, but just after a few minutes of walking my height goes back to 170 centimetres. 6 cm are like slightly more than 2 inches.
I wanna know how to keep a decompressed spine for longer after doing dead hangs. With shoes on and a decompressed spine I'm an average height person and a shoter than average person...kind of sucks that the spinal decompression doesn't last much.
