the lessons for sure need to be regular for a bunch of time spaced with time to 'really train in the changes' those changes
reason they often times have better outcomes in the lesson is you have guidance to make sure the 'stuff' is in good shape before the swing gets put on the ball
real proper training practice alone is an issue often times because of 'feel to real' and that something that most folks struggle with this
so often times in their own training sessions folks hit balls truly thinking those changes are being worked on but to start off with most times they are not exactly as 'new stuff' tends to slip back a tad to comfy while also still trying to swing at full steam ahead - as opposed to 60%-70% swing effort to give tad more 'time' to sequence new stuff up
would say would be worth giving some thought into investigating just how best to train in practice - like putting alignment sticks down so both body alignments and ball position can really be where they all should be as there's some visual check points
and making sure the hold on the handle does not slip back to comfy all that kinda stuff - have to think around monitoring training sessions so not relying purely on 'feel to real' as it's a fickle training partner
most folks have cells so video the grip, set-up, swings, alignments all of that stuff (shoot from front on and dtl - get some reference of both angles from the lesson sessions so you have a 'models' to work to and compare the stuff being done in the training practice)
for sure get some quicker results if some rigor is given to the real monitoring of what's going down in training
mostly when starting the sessions any swing motions would be better worked feeling the motion needed in slow motion first off
then follow with a half speed rehearsal swing
then swing through a ball but only at 60% (having checked all the stuff grip, set-up, posture, aim, alignments, ball position)
it's a ways impossible to try make changes just trying to hit everything spark out with no real way of monitoring what is actually goin down in the training sessions - think of it as training not practice as the main purpose first off is to change stuff - can make training interesting and enjoyable as well
put some good work in the reward is better results out in play
