I have taught Martin Young for 25 years & his lowest handicap has been +4.
Martin had a lesson recently & we revised his stance & the first movement to start the back swing.
Martin rang me a few weeks later to thank me for the lesson and said he had just scored a gross 63.
If all golfers continually checked their stance & the first part of their back swings I can guarantee their scores would come down.
Please try it & you will be pleasantly surprised.
