Not gonna lie this is pretty brain twisting and my right hand feels destroyed cause i have this problem on my ring finger. But no way was i near as fast as this guy. Any of you seen this or done it for a period of time? There are some decent exercises in this that i have come across that help warm up your hands and fingers. Going to try to do this more often see if it helps with my right hand on the piano cause it feels super weak compared to my left.
if anything it will give you a good laugh at how insanely difficult this is and is he an alien?
