You can see from the picture that this was not going to end well.
I think where it went wrong was as i was trying to bring my head and chest through into vrshchikasana my arms began to bend a little and of course as I went over they just bent further and further offering no support
I actually don't mind these so much. Landing on your head is probably what we're most worried about, but when it happens it's not as bad as you fear. Sounds worse here because of the floorboards.
Thought slow motion would be amusing.
