I'm not clear on what the exercise is supposed to do?? Scott Herman is a content creator....that's how he earns a living so there is always going to be something new from him that you must be doing.....but bending over backwards doesn't do anything. There was a bit of isometric holding in the quads but you could get that in the same degree from just stooping....although the quads are such a massive and active muscle grouping isometric work for them isn't really something you would deem necessary.
