spot on m8, lolololololol 'pronation and elbow separation' n dat's why 1/2 of the 'tennis players' have/had well cooked tennis/golf elbows for dinner all the time..........read dat from an research journal a few yrs ago..................Here is my severely tunnel-visioned take on coaching recreational players.
I remember my university admission exam. It was a mixture of all disciplines. Athletics, gymnastics, basics of almost every game. It all came astonishingly easy to me, except one thing, stupid swimming.
That was the one discipline I actually had to train for to even be within the limits. And even with the training, I finished hundreds of places bellow the top scorers.
I am just not a water creature. I have not set foot into the pool ever since. Never for a second have I thought about hiring a professional or devoting thousands of hours and dollars to becoming a better swimmer.
There are thousands of sporty endeavours out there. Inevitably, you will be good at one of them. It continues to fascinate me with how much masochism people are engaging in something they clearly have no talent for.
I would even go as bold as saying that if your average 4.5 tennis youtuber does not seem laughably terrible to you, you have very little chance of ever being any good at this.
Now you can either accept it and go have fun on the court, which is perfectly ok with me, or you can forever keep paying someone to work on your pronation and elbow separation.
