As you say, training is required. Just saying column fully forward and opposite rudder, is very generalised. It doesn’t include the checklist items of throttle to idle, ailerons neutral, rudder full opposite and then forward elevator (as per the manual). Training with a competent instructor will explain exactly why all those four steps are needed and the difference between an incipient, fully developed spin, and a spiral dive ( and discuss inverted spins).
it’s a bit like saying Instrument Flying is just staring at the Artificial Horizon most of the time….
