I thought years ago I invented this system
I literally made it up, then thought of the same name
Freaky when I saw exactly the same thing later on
I always think maybe I saw it somewhere, but forgot, but this little voice keeps going "You KNOW you didn't!". Maybe there's something to this telepathy thing
I think it can work, as it seems to for some. I reckon it might well overtrain some individuals if they squatted, did O-lifts, etc, but for chins I think it could well work (as long as you didn't suffer any overuse injury) & focussed on one goal (like 20 chins etc), while keeping the rest of your training balanced.
