Those are the standard ki soc warmup exercises, we do them most lessons here,
But then again, most Aikidoists have seen those exercises at some time and most Ki-Society dojos have them as part of their syllabus. Most people don't understand them, do them wrong, or do them with some major gaps. I pointed them out numerous times on this forum as being fine exercises, once someone knows how. Your position has always been that you already know and do all this stuff, so I say "go for it".
