I think you can relate to why the other members critic this video. It shows next to nothing. If you want to make a point just do some heavybag work and put your mobile next to it. Not that difficult and you dont need anyone else.
If you dont want to do that its fine but then I recommend you tone down your claims by a lot.
I don't have access to a boxing bag unless the instructor wants it, which is totally irregular. Once we're done, the next group enters. No room for a bag it in my apartment either.
