Tapio,
Nobody is saying you can't take a golfer, any golfer, and work on the whole swing from the start of the lessons.
Teaching them all the body movements, then training them to precisely go through a "building Blocks" type of arm/hand/club training, and that you can do ALL of that without a ball.
And then, and only then, let them start hitting balls.
I used to do pretty much all of that, just like that.
I don't anymore.
I still do
I used to teach a flat swing. I don't really do that much anymore either.
I don't teach flat, flattening yes
I used to teach massive lag and bowing the left wrist to just about everyone, I teach it to a very small percentage now.
Not for many either. More that or less that for many
I taught some folks a steep shoulder turn for a while as well.
Never done that
Don't do that anymore either.
Are you curious to why?
Not really, because I go case by case
We get results too.
One student moved 80 places up the world ranking last year.
Congratulations But why only one?
BTW, what Flightscope do you have?
